What type of angle does complementary angles form?
a right angle
What is the distance in units between the points (-5,7) and (-5, -8)?
15 units
The sum of the interior angles of any triangle is always this number.
180 degrees
If a triangle has angles measuring 50° and 60°, this is the measure of the third angle.
70 degrees
A triangle has side lengths 3, 4, and 8. According to this rule, does this create a triangle? How do you know?
No, because 3+4 = 7 and that is not greater than the third side, 8.
A triangle has one right angle and an angle that is 30 degrees? Find the third angle.
60 degrees
The sum of two angles in a triangle is 130 degrees. What is the measure of the third angle?
50 degrees
Angle X and Y are supplementary angles. The measure of angle X is 3n - 18. The measure of angle Y is 2n - 27. What is the measure of angle X.
117 degrees
x = 11
A triangle has angles 2x, 3x, and 4x. Create an equation to solve for the value of x.
x = 20
