Inside an ancient temple, Emek and Luna found three stone doors, each marked with a different corner shape. Using their angle-measuring tool, they discovered the first door showed a 55° angle, the second a 90° angle, and the third a 125° angle. A clue on the wall said, "Choose the door with the right angle first, then the door with the obtuse angle." They identified the correct doors by measuring and naming the angles. The hidden passage opened, leading them safely to a chamber filled with sparkling treasure.

Hint
A right angle measures exactly 90°.
The temple clue said to choose the door with the right angle first. Which door should Emek and Luna choose?
The 55° doorThe 90° doorThe 125° doorAny of the three doorsCorrect! A right angle is exactly 90°.
Remember that a right angle always measures 90°.

Hint
Subtract the smaller angle from the larger angle.
The first door measured 55° and the third door measured 125°. What is the difference between these two angle measures?
Correct! The difference is 70°.
Find how many degrees more 125° is than 55°.

Hint
An obtuse angle is greater than 90° but less than 180°.
After opening the right-angle door, the clue said to choose the obtuse angle. Which door should Emek and Luna choose next?
The 55° doorThe 90° doorThe 125° doorThere is no obtuse angle.Correct! 125° is an obtuse angle.
Look for the angle that is greater than 90° but less than 180°.
