What are measures of the exterior angles?
Subtract the interior angle by 360 degrees
What is the measure of the unknown angle?
you add them then subtract by 180 to find the unknown angle
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
A polygon whose angle measurement add up to 360 degrees?
what polygon has angle measures that add up to 360
How do you Calculate the right angle of a triangle?
Al you need to get is a protractor to measure it really. say you had a straight line you know how much that measures and you know how much the other angle measures so subtract it and you have the answer!
The measures of the three angles of a quadrilateral are 80 140 55 find the measure of the fourth angle?
the angle measures of a quadrilateral must equal 360 degrees so you add 80+140+55=275 then subtract from 360. the answer is 85
What are the methods used to compute the measures of complementary and supplementary angles?
The methods are subtraction. -- Subtract an angle from 90° to find its complementary angle. -- Subtract an angle from 180° to find its supplementary angle.
What are measures of the exterior angles?
Subtract the interior angle by 360 degrees
How do you find the measure of an angle in a triangle?
Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.
What is the measure of the unknown angle?
you add them then subtract by 180 to find the unknown angle
If one angle of a triangle measures 32 degrees and another angle measures 71 what is the measure of the third one?
32 and 71 equals 103 subtract that from 180 and you get your answer of 77 degrees
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
A polygon whose angle measurement add up to 360 degrees?
what polygon has angle measures that add up to 360
How do you Calculate the right angle of a triangle?
Al you need to get is a protractor to measure it really. say you had a straight line you know how much that measures and you know how much the other angle measures so subtract it and you have the answer!
What is the sum of the angle measure of the regular pentagon?
Each exterior angle measures 72 degrees and they add up to 360 degrees Each interior angle measures 108 degrees and they add up to 540 degrees
How do you determine the fourth angle of a quadrilateral if three angle are known?
Add up the three angles and subtract that from 360.
Angle A and angle B are supplementary angle then angle A is a what of angle B?
they add up to 180 so it depends. you have to know one of the measures
