5 Types of Triangles & Parts of Triangles
Transcript of 5 Types of Triangles & Parts of Triangles
Acute Triangle & Obtuse Triangle
A acute triangle is where all angles measure less than a right angle or 90 degrees.
An obtuse triangle is a triangle that has an angle more than 90 degrees.
Isosceles Triangle & Equilateral Triangle
Right Triangle & Scalene Triangles
Median of a Triangle
Median of a Triangle is a line segment joining a vertex of the triangle to the midpoint of the opposite side of the triangle. The three medians of a triangle are concurrent and the concurrent point is called the centroid of the triangle.
("Median of a Triangle," n.d.)
A isosceles triangle is any triangle that has two sides that are the same length.
A equilateral triangle is a triangle where all three sides are the same length.
Altitude of a Triangle
Formally, the shortest line segment between a vertex of a triangle and the (possibly extended) opposite side. Altitude also refers to the length of this segment.
Bisector of a Triangle
The definition of the perpendicular bisector of a side of a triangle is a line segment that is both perpendicular to a side of a triangle and passes through its midpoint.
Identify the median of the triangle.
Draw an example of altitude, median, and bisector of a triangle.
