What is a right triangle?
A triangle with one 90 degree angle.
A triangle in which its angle equals 180 degrees.
It's actually called a left triangle, not a right triangle.
A triangle in which its angle equals 360 degrees.
What are the names for each side on a right triangle?
A: leg; B: Hypotenuse; C: Leg
A: Hypotenuse; B: Leg; C: Leg
A: Leg; B: Leg; C: Hypotenuse
A: Leg; B: Leg; C: Leg
Based on the previous answer choice, why is "C" called the hypotenuse of a right triangle?
Because it equals 90 degrees.
Because it's the longest side on a right triangle.
Mathematicians got bored and just named it off the top of their heads. 😂
Because it's adjacent to the 90 degree angle.

How can you determine if a triangle is a right triangle?
If the sum of the legs squared is equal to the sum of the hypotenuse squared.
You can't tell.
If one length is greater than another
If one length is lesser than another
How can you determine if a triangle is obtuse?
When a2 + b2 is greater than c2 .
When a2 + b2 is equal to c2.
When a2 + b2 is lesser than c2.
Triangles are only right.
How can you determine if a triangle is acute?
When a2 + b2 equal to c2 .
When a2 + b2 is lesser than c2 .
They can only be right triangles.
When a2 + b2 is greater than c2 .

Solve for x and y.
x = 4√1; y = 64
x = 20√3; y = 40
x = 45√7; y = 12
