Mini Lesson Isosceles And Equilateral Triangles Jeopardy Template

Definitions	Types of Triangles and related definitons	Theorems and related definitions	Problems
100 Triangle What figure is formed by three segments and three non collinear points?	100 Isosceles triangle What is the name for the triangle that at least has two congruent sides?	100 Interior angles and exterior angles What is another name for a triangle's inside angles? What is adjacent to the those angles of a triangle?	100 x = 21 Find x using the corollary to the triangle sum theorem. Interior angles: 90 degrees, 3x + 4, x + 2.
200 Angles and sides What are two things needed to classify a triangle?	200 Equilateral triangle What is the name for the triangle that has 3 congruent sides?	200 The sum of the measures of the interior angles of a triangle is 180 degrees. Explain the triangle sum theorem.	200 x = 14 Find x using the exterior angle theorem. Interior angles: 54, 47 Exterior angle: 6x + 17
300 Vertex or vertices What are the three points that join at the sides of a triangle?	300 Hypotenuse What is the triangle's side called if its opposite from a side that has a right angle?	300 One exterior angle of a triangle is equal to the other two nonadjacent interior angles. Explain the exterior angle theorem.	300 x = 2.285 Find x using the corollary to the triangle sum theorem. Interior angles: 90, 14x + 36, 7x + 6.
400 Adjacent sides What are two sides called when they share a common vertex?	400 Legs What are the sides that form a right angle in a right triangle or are equal to each other in an isosceles triangle?	400 A right triangle is given with its other two angles missing. The two missing angles must be added together and then set to equal the right angle to find the missing variables and values. Explain the corollary triangle sum theorem.	400 x = 15 2/3 Find x using the exterior angle theorem: Interior angles: 50 + 2x, 7x + 51 Exterior angle: 15x + 15 - 8
