Is college math a lot of triangles? ( please answer)

A triangle is a three-sided figure whose angles always add up to 180°. Thus, ∠x +∠y + ∠z = 180°.

The largest angle of a triangle is opposite its longest side.

On the SAT, the triangle to the left would be referred to as triangle abc or ∆abc.

To find the perimeter of the triangle, add up all the sides (a + b + c).

To find the area of any triangle, use the formula, (1⁄2)bh. The height must be perpendicular to the base.

Two triangles are similar if their angles have the same measure. The triangles therefore have the same shape, and their sides will be in proportion.

Triangles are said to be congruent if they have the same shape and size.

Equilateral Triangles

Equilateral Triangle

An equilateral triangle has three equal sides. Thus: a = b = c.

An equilateral triangle has three angles are also equal. Thus, ∠x = ∠y = ∠z.

Since the angles of a triangle always add up to 180°, each angle of an equilateral triangle must also equal 60°. Thus, ∠x = ∠y = ∠z = 60°.
