Transcript of Geometry!
A line drawn through a concave polygon, depending on exactly where you draw it, can intersect the polygon in two or more places.
A polygon with one or more interior angles greater than 180°. It looks sort of like a vertex has been 'pushed in' towards the inside of the polygon.

A shape with five sides. They can be drawn many different ways.
The Superman emblem is a pentagon, as it has five sides.
An equilateral triangle is a triangle with all three sides of equal length. An equilateral triangle also has three equal 60 degrees angles.
This Iron Man arc reactor is designed to look like an equilateral triangle.
A Parallelogram is a flat shape with opposite sides parallel and equal in length.
The polygons made when Wolverine crosses his claws in an 'X' formation are parallelograms.
Two angles are adjacent if they have a common side and a common vertex, and they don't overlap.
Angles one and two in this 1941 Batman logo form a pair of adjacent angles.
A parabola is a curve where any point is at an equal distance from a fixed point and a straight line.
In these pictures; if the arrow head is the fixed point and the arrow itself is the line, then the bow is the parabola.
Two circles can intersect either, at a single degenerate point, or at two distinct points. The most common version of intersecting circles is a Venn Diagram.
When it is swung around, Wonder Woman's Lasso of Truth can
form intersecting circles.
Negative Sloped Line
A negative slope demonstrates a negative correlation. Negative correlation occurs when the two variables of a function move in opposite directions. A line moving from the left to the right, on a graph or grid, will move downward, if it has a negative slope
The downward angle of the web that Spiderman is holding indicates that it is a negatively sloped line.
Lines that are at or intersect to form a right angle; a 90° angle.
Right angles can be represented by a square box placed in the indicated angle, as shown in the Martian Manhunter emblem.
A solid (3-dimensional) object which has six faces that are rectangles.
Utility belts all have small rectangular prism shaped compartments used to hold a variety of handy items and tools.
A circle is a shape made by drawing a curve that is the 'radius' away from a central point.
Captain America's shield is in the shape of a circle.
Two or more lines that meet at a point are called intersecting lines. That point would, of course, be located on each of these lines.
This Fantastic 4 logo has a set of intersecting lines in it. While they are intersecting, these lines do not form right angles and therefore they are not perpendicular to each other.
An obtuse angle is an angle which is more than 90° but less than 180°. In other words, it is between a right angle and a straight angle.
This Blue Beetle logo, the antennas specifically, form an obtuse angle.
Congruent Angles have the same angle measurement, either in degrees or radians. They don't have to point in the same direction or be on similar sized lines.
On this Wonder Woman Symbol there are two sets of congruent angles. As shown by the semi-circles that indicate angles congruency.
A linear pair is two angles that are adjacent and whose measurements are supplementary (add up to 180°).
The first part of the Avengers 'A' is a straight line, the arrow that cuts across it, forms two linear angles; a linear pair.
Linear Pair of Angles
Triangles are similar if they have the same shape, but they can be different sizes. They are still similar even if one is rotated, or one is a mirror image of the other.
DC Comics animation uses domino masks, these create triangle shapes that cover the eyes of the wearer. The triangles created are similar to each other.
When two parallel lines are crossed by another line, the transversal, the pairs of angles on opposite sides of the transversal, still inside the parallel lines, are called Alternate Interior Angles.
The 'H' in "Hulk" presents a set of parallels and a transversal, as well as a set of alternate interior angles.
Alternate Interior Angles
The two planes that meet in a single line are called intersecting planes. Two planes cannot intersect in more than one line.
When Hawkman's wings intersect his back, they come together at one spot and form a single line. Thereby creating intersecting planes, with each other and his body.
Two nonparallel lines in space that do not intersect are called skew lines.
Since we've discovered wings are intersecting planes two lines on opposite planes are skew lines. Meaning that, the lines created by the feathers on Hawkgirl's wings can, essentially, be considered skew lines.
Rotation means turning around a center. Here's a picture of a
geometric shape rotated:
If someone moves from a standing position to a
position where they are flying horizontally or diagonally then they have rotated from their original position.
Have A Good Day!
Watch out For Smashing Hulks' and Flying Thors'!
