FLASHCARD QUESTION
Front
What is the Triangle Sum Theorem?
Back
The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.
2.
FLASHCARD QUESTION
Front
If two angles of a triangle are 56° and 37°, how do you find the third angle?
Back
Subtract the sum of the two angles from 180°: 180° - (56° + 37°) = 87°.
3.
FLASHCARD QUESTION
Front
What is the measure of the third angle in a triangle if one angle is 81° and another is 37°?
Back
The third angle is found by: 180° - (81° + 37°) = 62°.
4.
FLASHCARD QUESTION
Front
How do you calculate the value of an unknown angle in a triangle?
Back
Use the Triangle Sum Theorem: 180° - (sum of known angles) = unknown angle.
5.
FLASHCARD QUESTION
Front
What is the measure of an angle if the other two angles in the triangle are 90° and 82°?
Back
The measure of the angle is: 180° - (90° + 82°) = 8°.
6.
FLASHCARD QUESTION
Front
If one angle of a triangle is 45° and another is 75°, what is the third angle?
Back
The third angle is: 180° - (45° + 75°) = 60°.
7.
FLASHCARD QUESTION
Front
What is the relationship between the angles in a triangle?
Back
The angles in a triangle are related such that their sum is always 180°.
