400
If you have a right triangle with an an acute angle of 35 degrees, what is the measure of your third angle?
What is 55 degrees
400
The angles of a quadrilateral add up to what degree?
What is 360 degrees
400
True or False: You can have a circle with three of the interior angles measuring 150, 150, and 40 degrees
False. There are four interior angles in a circle and there are two pairs of equal angles. 150 and 150 are vertical angles that add up to 300 degrees. 40 is a vertical angle also so the missing angle equals 40 degrees. If you add those, it makes 80 degrees. Altogether, your angles measure 380 degrees, but circles measure 360 degrees

What is two rays that meet at an endpoint
500
If one angle measures 110 degrees, what is the measure of the angle vertical to it?
What is 110 degrees

Double Jeopardy! Name the two ways we classify triangles and name every type of triangle in the catergory.
What is sides and angles. Sides: Isosceles, Scalene, Equilateral. Angles: Acute, Obtuse, Right
500
If you have a parallelogram with an obtuse angle of 112 degrees and an acute angle of 68 degrees, can you determine the measure of the two remaining angles? Why or why not?
A parallelogram has 2 pairs of equal sides, meaning there are two pairs of equal angles. The two missing angles are 112 and 68 degrees
