Understanding Triangle Angle Sums

What is the sum of the interior angles of any triangle?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees

If a triangle has angles measuring 45 degrees and 90 degrees, what is the measure of the third angle?

• 30 degrees

• 45 degrees

• 90 degrees

• 60 degrees

In the example problem, what is the value of x if the angles are 52 degrees, 34 degrees, and x?

• 86 degrees

• 76 degrees

• 94 degrees

• 104 degrees

What operation is used to isolate x in the equation 86 + x = 180?

• Addition

• Multiplication

• Subtraction

• Division

If you find a mistake in your solution, what should you do?

• Go back and try to find the mistake

• Move on to the next problem

• Ask someone else to solve it

• Ignore it
