Semester 2 Final Review 2020-2021

What is the longest side of a right triangle called?

• Leg A
• Leg B
• Hypotenuse
• Pythagoras' Big Buddy

Determine if the following set of numbers are Pythagorean Triples.
15, 20, 25

• Yes
• No

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?

• $17^2+8^2=b^2$

• $8^2+b^2=17^2$

• $17^2+b^2=8^2$

• $\frac{8^2}{b^2}=\frac{17^2}{100}$

The longest side of a right triangle is DIRECTLY ACROSS from the...

• right angle.
• acute angle.
• obtuse angle.

Find the length of the missing side. 

• 17 cm
• 22 cm
• 15 cm
• 13 cm

Sides a and b are called legs.

• true

• false

State if the 3 sides form an acute, obtuse, or right triangle.

9, 14, 15

• acute

• right

• obtuse

State if the 3 sides form an acute, obtuse, or right triangle.

3, 12, 13
