Special Right Triangles: Worksheet Special Right Triangles 45-45-90

Special right triangles are triangles with specific angle measures that give them unique properties. One of the most common special right triangles is the 45-45-90 triangle.

45-45-90 Triangles, Worksheet special right triangles 45-45-90

A 45-45-90 triangle is a right triangle with two 45-degree angles and one 90-degree angle. This type of triangle has several important properties:

• The ratio of the side lengths is always 1:1:√2.
• The area of the triangle is always (1/2) – base – height.

Pythagorean Theorem

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

This theorem can be used to find missing side lengths in 45-45-90 triangles.

Angle Relationships

The angle relationships in 45-45-90 triangles are also important.

• The two 45-degree angles are always opposite the two congruent sides.
• The 90-degree angle is always opposite the hypotenuse.

These angle relationships can be used to solve problems involving 45-45-90 triangles.
