Parallel lines with a perpendicular transversal

Parallel lines with a non-perpendicular transversal

This diagram shows parallel lines with a non- perpendicular transversal. As you can see in this picture the bottom and the top of the table are parallel, and the metal part going diagonal across the table is non perpendicular.

Vertical angles formed by two intersecting lines

This diagram shows vertical angles formed by two intersecting lines . The crack in between the bathroom tiles form a vertical angle by intersecting.

Parallel lines with No transversal

example

This diagram shows parallel lines with a no transversal. As you can see in the blinds, there are parts that just go straight.

Definition :

Lines that goes straight forever and will never intersect

example

Supplementary adjacent angles formed by two intersecting lines

This diagram shows supplementary adjacent angles formed by two interesting lines. On this gate the wooden bottom is one line and it intersects with the other part of the gate that goes diagonal. Those two angle add up to 180.

Complementary adjacent angles formed by two intersecting lines

This diagram shows complementary adjacent angles formed by two intersecting lines. As you can see on the fence there is on part going vertical, and one part going horizontal on the bottom of the fence. There is a part of the fence where the vertex is and it is going diagonal from the vertex. The line vertical and the line horizontal intersect causing two adjacent angles to be formed.

vertex

30+60=90

Acute angle

This diagram shows a acute angle, which is less than 90 degrees. The inside part of the hanger is acute

less than 90 degrees

Right angle

This diagram shows a right angle. As you can see one of the cracks on the door goes straight up, and the other crack is horizontal. The horizontal crack is on the bottom.

90 degrees

Obtuse angle

This diagram shows a obtuse angle. On the top of the door there is a triangle shaped roof, if we measured the degrees of the roof it would be grater than 90 degrees so it is a obtuse angle.

145+45=180

more than 90 degrees

Corresponding angles

This diagram shows a corresponding angle. On the bottom of the gate there is a wooden stick going across, then in the middle there is a wooden stick going across. Those to sticks are parallel, and there is also a wooden stick going diagonal through both of the parallel lines.

corresponding angles are always congruent to each other (equal)
