Is it a Right Triangle?

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What are the legs of a right triangle?

Back

The legs of a right triangle are the two sides that form the right angle.

Front

What is the hypotenuse?

Back

The hypotenuse is the side opposite the right angle in a right triangle and is the longest side.

Front

How can you determine if a triangle is a right triangle using side lengths?

Back

You can use the Pythagorean theorem: a² + b² = c², where c is the length of the hypotenuse.

Front

If a triangle has sides of lengths 6, 8, and 10, is it a right triangle?

Back

Yes, because 6² + 8² = 10² (36 + 64 = 100).

Front

Which side lengths can form a right triangle? 7, 12, 18; 6, 10, 8; 15, 7, 8; 1, 1, 2

Back

6, 10, 8 can form a right triangle.

Front

Which side lengths can form a right triangle? 3, 5, 6; 2, 8, 10; 3, 4, 5; 7, 12, 15

Back

3, 4, 5 can form a right triangle.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

If the sides of a right triangle are 40, 50, and 30, which sides are the legs?

Back

The legs are 40 and 30.

Front

What is the formula to find the length of the hypotenuse?

Back

c = √(a² + b²), where c is the hypotenuse and a and b are the legs.
