At first you don't succeed...'tri', 'tri' again!
Sadly, parallel lines were never meant to meet.
What do you call an empty parrot cage?
A pyramid is a prism without a face!
I need more cowbell!
100
This is a triangle that has three angles that measure less than 90 degrees.
What is an acute triangle?
100
This is a line that crosses at least two other lines.
What is a transversal?
100
This is a simple closed figure formed by three or more line segments.
What is a polygon?
100
This is where two planes intersect in a line.
What is an edge?
100
This is the distance around a circle.
What is circumference?
200
This is a triangle that has two sides of equal length.
What is an isosceles triangle?
200
These are the pairs of angles on opposite sides of the transversal, but inside the parallel lines.
What are alternate interior angles?
200
This is a polygon with four sides and four vertices.
What is a quadrilateral?
200
This is a polyhedron with one base that is any polygon; other faces are triangles.
What is a pyramid?
200
These are angles in which the sum of the angles measure 90 degrees.
What is complementary?
300
This is a triangle that has one angle that measures more than 90 degrees.
What is an obtuse triangle?
300
These are opposite angles formed by two intersecting lines and are congruent.
What are vertical angles?
300
This is a figure formed by three line segments, or parts of a line containing two endpoints, that intersect only at their endpoints.
What is a triangle?
300
This is a polyhedron with two parallel congruent faces called bases.
What is a prism?
300
This is the length of a line segment from one side of a circle to the other through the center.
What is diameter?
400
This is a triangle that has NO sides of equal length.
What is a scalene triangle?
400
These are the pairs of angles on opposite sides of the transversal, but outside the parallel lines.
What are alternate exterior angles?
400
This is a quadrilateral with one pair of opposite sides that are parallel.
What is a trapezoid?
400
This joins two vertices that have no faces in common.
What is a diagonal?
400
These are angles in which the sum of the angles measure 180 degrees.
What is supplementary?
500
This states that the sum of any two sides of a triangle must be greater than the measure of the third side.
What is the Triangle Inequality Theorem?
500
These are angles that share a vertex and a side.
What are adjacent angles?
500
This is a quadrilateral in which both pairs of opposite sides are parallel and has opposite angles of equal measures.
What is a parallelogram?
500
These are lines that are neither intersecting, nor parallel.
What are skew lines?
500
This is the length of a line segment from the center of a circle to the edge.
