Given that line EF is parallel to line GH and line AB and line CD are parallel, which angles are proven congruent by alternate exterior angles?
Prove that triangle ABC is congruent to triangle DBE. Given: line AE bisects line CD and side AC and side DE are congruent.
This diagram is not drawn to scale! What would the last angle in this square have to be in order to be a quadrilateral? Then, find the angle measurement of the exterior angle.
Prove triangle ACD and triangle ACB congruent. Given: AC bisects angle a and angle c. Side AD is congruent to side AB
The rectangle is in a pattern made of identical shapes...What is this called?
What shape is this? Find the other angle measurements.
Assume these are lines... Would they be parallel, oblique, or skew?
Choose the method that explains why triangle ABC is similar to triangle DEF.
A) AA B) SSS C)SAS D) not possible
What kind of triangles are these? If angle d and angle a are congruent, what postulate would you use to solve these congruent?
How many diagonals could be drawn in this octagon?
1. 1&16, 13&4
line AE bisects line CD
Vertical angles are congruent
side AC and side DE are congruent.
3. 74 & 106
AC bisects angle a and angle c.
Side AD is congruent to side AB
6. 150 degrees
8. not possible
9. isosceles & ASA
