Is it 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 (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). It is expressed as: a² + b² = c².

Front

Which triangle does the Pythagorean Theorem apply to?

Back

The Pythagorean Theorem ONLY works on right triangles.

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, typically referred to as sides a and b.

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle, and is represented by side c.

Front

If a triangle has sides of lengths 15, 12, and 9, does it form a right triangle?

Back

Yes, the sides 15, 12, and 9 form a right triangle because they satisfy the Pythagorean Theorem: 9² + 12² = 15².

Front

Is side c always the longest side in a right triangle?

Back

Yes, side c is always the longest side in a right triangle.

Front

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

Back

To find the length of the hypotenuse (c), use the formula: c = √(a² + b²).

Front

Can a triangle with sides 5, 12, and 13 be classified as a right triangle?

Back

Yes, because 5² + 12² = 13² (25 + 144 = 169).

Front

What is the relationship between the angles in a right triangle?

Back

A right triangle has one angle that measures 90 degrees, and the other two angles must add up to 90 degrees.

Front

What type of triangle has two equal sides?

Back

An isosceles triangle has two equal sides.
