Question
Answer
acute angle   an acute is an angle whose mesure is between 0 and 90.  
🗑
angle   an angle is formed by two rays with the same endpoint. the rays are side of the angle and comon endpoint is the vertiz of the angle.  
🗑
angle bisector   an angle bisector is a ray that divides an angle into two congruent angles.  
🗑
collinear points   points that lie on the same line.  
🗑
congruent   anglesangles that have the same mesure  
🗑
congruent segments   segments that have the same lenth  
🗑
conjectur   a conclusion reach by inductive resoning  
🗑
coordinate    
🗑
coplanar   coplaner are figure in the same plase.  
🗑
counterexample   a statment that particular example or instence of the statement that makes the statment false.

🗑
postulare   an acceoted statement or fact  
🗑
ray   a ray is a point of a line consisting of one endpoint.  
🗑
right angle   a right anngle is an angle whose mesure is 90
