Can you have more than one obtuse angle in a triangle? Explain.
Can you have more than one right angle in a triangle? Explain.
Can you have more than one acute angle in a triangle? Explain.
How many degrees are in a triangle?
If one triangle has angles 90, and 45 what is the third angle?
What can you say about the two other angles in a right triangle? (Besides the fact that they must be acute)
If a triangle has angles with degrees 100 and 32, what is the third angle?
Drag the points around. What do you notice about the remote interior angles and the exterior angle?
Create a triangle. Note their angles and the exterior angle measurement.
Create a triangle with angles 45, 45, 90. What is the exterior angle?
Create a triangle with 35, 55, 90. What is the exterior angle?
