Unit 4 Practice Test P6

Front

What is the longest side of a triangle located across from?

Back

The longest side of a triangle is located across from the largest angle.

Front

Solve for x: 2x + 3 = -5

Back

x = -4

Front

Can a triangle have sides: 4, 6, 10?

Back

No, these sides cannot form a triangle.

Front

Which side lengths would NOT form a triangle? {2,5,9}

Back

These lengths do not satisfy the triangle inequality theorem.

Front

Find the lengths AD and BC if they are proportional to 12 and 16 respectively.

Back

AD = 12; BC = 16

Front

What is the triangle inequality theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What is the relationship between the angles and sides of a triangle?

Back

The largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

If a triangle has sides of lengths 3, 4, and 5, what type of triangle is it?

Back

It is a right triangle.
