Lesson 4: Understanding angle measurement

Angles in circles word problems

Practice word problems that involve thinking about angles as part of a circle.

Problem 1: Caterpillar

A caterpillar stands on her head.
How many degrees does the caterpillar need to turn to be upright?
${}^{\circ }$

Problem 2: Oven

If Arianna turns the stove dial ${135}^{\circ }$ to the right, what setting will the dial be on?

Problem 3: Directions

Melissa walks $3$ blocks south. Then she turns ${45}^{\circ }$ right (clockwise) and walks $1$ block.
What direction does Melissa end up facing?

Problem 4: Pizza

A pizza is cut into $6$ equal slices.
How many ${1}^{\circ }$ turns does it take to make $1$ slice of pizza?
turns

Challenge problem: Clock

How many degrees does the hour hand on a clock turn between $7:00$ AM to $10:00$ AM?
${}^{\circ }$

• The clock one was the hardest. Does anyone agree?
• I agree it is hard. I got confused
• Probably should have used a different term than "turns".
• for real
• The clock one was the hardest out of all
• It would seem as though for each one we take the number of times (it occurs) / the number of objects there are.
In the clock problem (between 7 o'clock and 10 o'clock, there is 3 hours) we know that a clock has 12 hours which can be written as 3/12 -> 1/4. 360 / 4 = 90
• The clock problem is the one I found easiest except for the worm problem. Is this just me or...?
• honestly i found the clock problem to be the hardest
• This doesn't make any sense whatsoever. It has to make at least one full turn to get to another hour. Plus another 30 degrees to get to the next hour! How is 90 degrees possible? I went through a ton of trying to solve this problem. How is 90 degrees even the answer?
• Really, i believed the 90 degree answer, because is just saw it as a 'square corner'.
