What postulate proves these two triangles congruent?
What would the length of the third side have to be?
What makes these angles congruent? What would be the sum of all the angles?
What makes these two angles congruent?
What postulate is used to prove these two triangles congruent?
The measure of angle 1 is 74 degrees. What is the measure of angle 2?
If the measure of the angle is 84 degrees then is the angle acute, obtuse, or right? How do you know?
What would the length of the third side have to be for a triangle? How do you know this?
Are these two roads parallel, perpendicular, or skew?
Are these columns parallel, perpendicular, or skew?
Question 1: SSS postulate (Side Side Side)
Question 2: Between 4 and 28
Question 3: Vertical Angles, 360 degrees
Question 4: Alternate Interior Angles are congruent
Question 5: SAS Postulate (Side Angle Side)
Question 6: 106 Degrees
Question 7: Acute because the angle is under 90 degrees
Question 8: Between 5 and 29, we know this because any two sides combined have to be more than the third side.
Question 9: Perpendicular
Question 10: Parallel
