Question 1

What is the area of a triangle?

Answer 1

1/2 (b)(h)

The height is always perpendicular to the base.

Question 2

What is the measurement of the short leg, long leg, and hypotenuse with respect to x of a 30-60-90 triangle?

Answer 2

Short leg is x, long leg is x sq root of 3, and hypotenuse is 2x.

If a 90 degree triangle has the ratio of the hypotenuse to short leg as 2:1, you know it’s a 30-60-90 triangle.

Question 3

What is the length of the 2 legs and hypotenuse as it relates to x?

Answer 3

Legs are x and hypotenuse is x sqroot of 2

Question 4

Why is the 45-45-90 triangle (isosceles) special?

Answer 4

It is half of a square, so if you know the diagonal or side of a square, you can find the length of the square

Question 5

Answer 5

2 * r

Question 6
