# Triangles

Students will identify and describe types of triangles and their special segments. They will use logic to apply the

properties of congruence, similarity, and inequalities. The students will apply the Pythagorean Theorem and

trigonometric ratios to solve problems in real world situations.

## Trig Function Ratios 2 (En Español)

SLE T.2.G.6 – Use trigonometric ratios (sine, cosine, tangent) to determine lengths of sides and measures of angles in right triangles including angles of elevation and angles of depression.

## Special Right Triangles 3 (En Español)

SLE T.2.G.5 – Use the special right triangle relationships (30˚-60˚-90˚ and 45˚-45˚-90˚) to solve problems.

## Pythagorean Theorem 2 (En Español)

SLE T.2.G.4 – Apply the Pythagorean Theorem and its converse in solving practical problems.
