What is the measurement of the angles?
Angles greater than 0 but less than 90 degrees are acute angles. A 90 degree angle is a right angle. Angles greater than 90 but less than 180 degrees are obtuse angles. Angles greater than 180 but less than 360 degrees are reflex angles. A complete rotation of 360 degrees is a full turn.
Why are vertically opposite angles equal?
This would be much easier with a pic, but since I cant draw one for you here, you will need some imagination. Let us take 2 lines and create vertical angles at the intersection of those lines. I am going to call the pairs of vertical angles A, A' and B and B' where A and A' are vertical and B and B' are vertical. Now in your drawing notice that the sum of the degrees of A and B is 180 degrees, they are suplementary. But the sum of A and B' is also 180 degrees. So this means that the measure of B is equal to the measure of B'. We can do the same with A and A'.
What do you call polygons in which all sides have the same length and all angles have the same measure?
regular
What do you call polygons in which all sides have the same lenght and all angles have the same measure?
They are called regular polygons
If one angle is 10 more than 3 times as large as another angle which is complementary to it what is the measure of the smaller angle?
The smaller angle is 20 degrees and the larger is 70 degrees. Complementary angles total 90 degrees. Let's call the smaller angle A. The other angle is 3A + 10. The sum of both angles is 90, so 4A +10 = 90, 4A = 80, A = 20. The larger angle is 3(20) + 10 = 70.
What do you call an angle that measures 90 degrees?
Right angles measure 90 degrees. Angles less than 90 are called acute, and angles greater than 90 are called obtuse. Once you reach 180 degrees, you have formed a straight line. 360 degrees makes a circle.
What do you call angles that measure more than 360 degrees for example a 370 degree angle?
It's a reflex angle
What do you call angles that are the same?
Angles that have the same measure are called congruent angles.
What do you call a two angles if their measurement is 180 degrees?
They are supplementary angles.
What do you call 2 angles that add up to 180 degrees?
182
What do you call two angles that equal 180 degrees?
a line or supplementary angles.
What do you call a triangle with 0 angles of equal degrees?
You call It NOTHING
What angles have 47 degrees?
the angle is call and obtuse
What do you call angles with a sum of 180 degrees?
supplementary
What is the measurement of the angles?
Angles greater than 0 but less than 90 degrees are acute angles. A 90 degree angle is a right angle. Angles greater than 90 but less than 180 degrees are obtuse angles. Angles greater than 180 but less than 360 degrees are reflex angles. A complete rotation of 360 degrees is a full turn.
What do you call a parallelogram with internal angles of 90 degrees?
A rectangle.
What do you call a triangle with congruent angles?
An equilateral triangle has 3 congruent angles that add up to 180 degrees.
