What is a complementary angle?

500

Does a 38 degree angle and another 142 degree angle make a complementary or supplementary angle?

What is a supplementary angle?

True or false

100

Angles of 65 degrees and 25 degrees make a complementary angle.

True, 65 + 25 = 90 degrees.

200

Angles of 121 degrees and 69 degrees make a supplementary angle.

False, 121 degrees + 69 degrees = 190 degrees

300

Angles of 109 degrees and 71 degrees make a complementary angle.

True, 109 + 71 = 180 degrees.

400

Angles of 46 degrees and 64 degrees make a complementary angle.

False, 46 degrees + 64 degrees = 100 degrees.

500

A circle is 360 degrees.

True. To prove it, if you divide a circle into four equal parts each angle looks like an "L" which is complementary or 90 degrees. So, 90 degrees x 4 angles = 360 degrees or 90 degrees + 90 degrees + 90 degrees + 90 degrees = 360 degrees. (If you only make it halfway around a circle it is 180 degrees because you take 360 degrees divided by 2 equals 180 degrees or 90 degrees + 90 degrees = 180 degrees and it makes a straight line across the circle.)

Can two complementary angles equal a supplementary angle? Why or why not?

Yes, 90 degrees + 90 degrees = 180 degrees

200

Can two supplementary angles equal a complementary angle? Why or why not?

No, because 180 degrees + 180 degrees = 360 degrees

300

What shape does a 90 degree angle make?

An "L" shape

400

What shape does a 180 degree angle make?

A straight line

Knowing that a complementary angle looks like an "L" and is 90 degrees, how many interior degrees are inside a square or rectangle?

Total degrees inside the square/rectangle is 360 degrees because 90 degrees x 4 angles = 360 degrees or 90 degrees + 90 degrees + 90 degrees +90 degrees = 360 degrees. Extra Credit Daily Double: Since two triangles make up a square, how many interior degrees are inside a triangle?
