Triangle Similarity & Pythagorean Theorem

Front

What is the Side-Angle-Side (SAS) similarity postulate?

Back

It requires two sides and the included angle of one triangle to be proportional to two sides and the included angle of another triangle.

Front

What can be said about the corresponding sides of two similar triangles by the Angle-Angle (AA) postulate?

Back

They are proportional.

Front

What is the side of a right triangle across from the right angle called?

Back

Hypotenuse.

Front

Find the length of the missing side: If one leg is 30 and the other leg is 40, what is the hypotenuse?

Back

50.

Front

Find the length of the missing side: If one leg is 24 and the hypotenuse is 26, what is the other leg?

Back

10.

Front

What is the Pythagorean Theorem?

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).

Front

If two triangles are similar, what can be said about their angles?

Back

Their corresponding angles are congruent.

Front

What is the relationship between the sides of similar triangles?

Back

The lengths of their corresponding sides are proportional.

Front

What is the definition of a right triangle?

Back

A triangle that has one angle measuring 90 degrees.

Front

If the sides of a triangle are in the ratio 3:4:5, what type of triangle is it?

Back
