Right Triangle Similarity Theorem

What is the right triangle similarity theorem?

• The right triangle similarity theorem states that all right triangles are congruent

• The right triangle similarity theorem states that if a right triangle is placed inside another right triangle, then the two triangles are similar if the hypotenuse and one other side of the smaller triangle are proportional to the corresponding sides of the larger triangle.

• The right triangle similarity theorem states that the hypotenuse of a right triangle is always equal to the sum of the other two sides

• The right triangle similarity theorem states that the angles of a right triangle are always equal

Explain the concept of the altitude drawn to the hypotenuse of a right triangle.

• The altitude drawn to the hypotenuse of a right triangle is parallel to the hypotenuse.

• The altitude drawn to the hypotenuse of a right triangle is always equal to the length of the hypotenuse.

• The altitude drawn to the hypotenuse of a right triangle is also known as the median of the triangle.

• The altitude drawn to the hypotenuse of a right triangle divides the hypotenuse into two segments, and the length of each segment is the geometric mean of the lengths of the adjacent sides of the right triangle.

How can you use the right triangle similarity theorem to solve for unknown side lengths?

• Apply the Law of Sines to determine the unknown side lengths

• Calculate the area of the triangle to solve for the unknown side lengths

• Set up a proportion with the known side lengths and the unknown side lengths, then solve for the unknown side length using cross multiplication.

• Use the Pythagorean theorem to find the unknown side lengths
