Determine If a Triangle Is a Right Triangle

Why do we use the Pythagorean Theorem?

• To find the missing side of a right triangle
• To find the area of a triangle
• To find the volume of a cone
• To find the circumference of a circle

What is the formula used for the Pythagorean Theorem?

• a + b = c
• a² + b² = c²
• a₂ + b₂ = c₂
• a x b = c

What is the hypotenuse (c)?

• the two sides that make up the right angle
• the longest side, across from the right angle
• the shortest side
• the straight side of the triangle

What are the "legs" of a triangle (a + b)?

• the two sides that make up the right angle
• the longest side, across from the right angle
• the shortest side
• the straight side of the triangle

What is an example of squaring a number?

• 2 x 8
• 5 x 6
• 5 + 5
• 7 x 7

If a triangle has sides that measure 3 cm, 4 cm and 5 cm - is it a RIGHT triangle?

• Yes, right triangle
• No, not a right triangle

If a triangle has sides that measure 4 in, 5 in and 6 in - is it a RIGHT triangle?

• Yes, right triangle
• No, not a right triangle

If a triangle has sides that measure 4 in, 5 in and 6 in - is it a RIGHT triangle?

• Yes, right triangle
• No, not a right triangle

If a triangle has sides that measure 10 in, 4 in and 8 in - is it a RIGHT triangle? (be careful when you find c!)

• Yes, right triangle
• No, not a right triangle

If a triangle has sides that measure 8 mm, 17 mm and 15 mm - is it a RIGHT triangle? (be careful when you find c!)

• Yes, right triangle
• No, not a right triangle
