8.G.6-7 Check-Up Review

The side view of a ramp that Jessie built for his race cars is shown below. Find r, the length of the ramp to the nearest tenth.

Find the value of the unknown side.

Using the following image, what is the length of the missing side?

^{Find the missing side}

Do the segment lengths 9, 12, and 15 form a right triangle?

(HINT: a = 9, b = 12 and c = 15)

Given the lengths of a triangle are 6 in, 8 in and 10 in. Will this make a right triangle?

(HINT: "c" should be the longest side)

a = 2.1, b = 7.2,

c = 7.5

Is this a right triangle?

Which set of side lengths form a right triangle?
