What does all the measures of a regular polygon have to equal up to?
The exterior angles of any polygon add up to 360.
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
If one angle of a triangle measure 32 and another angle measures 71 what is the measure of the third angle?
77. The sum of the three angles in a triangle equal the sum of 180 degrees
What are the measures of the Base angles of an isosceles triangle whose vertex angle has measure of 70?
All angle sum to 180 degrees. Take 70 from this which leaves 110 degrees. The base angles must be equal so halve this number. Base angles are 55 degrees.
How many degrees does an isosceles triangle have?
An isosceles triangle has two equal angles and one different angle. The sum of the angles in any triangle is always 180 degrees. Therefore, the two equal angles in an isosceles triangle must add up to 180 degrees minus the different angle. So, each of the two equal angles in an isosceles triangle measures (180 - x) / 2 degrees.
Angles with equal measures?
congruent angles
Are measures of minor arcs equal measures of inscribed angles?
No. The first is a measure of length, the second is a measure of angular displacement. If you have two circles with arcs of the same angular measure, the lengths of the arcs will not be the same.
Two angles that have equal measures?
Are congruent angles.
What are angles with equal measures called?
Congruent angles
Angles that have equal measures?
Congruent
Which angles have equal measures?
90
What are angles that have the same degree measures?
They are equal (or 'congruent') angles.
What is a angle with equal measures?
Two angles with equal measurements are called congruent angles.
How do you know if angles are congruent?
If their measures are equal, then the two angles are congruent.
Is It true that angles whose measures are equal are vertical angles?
true
What are the two angles whose sum of measures is equal to two right angles are called?
supplementaryA:Two angles whose sum measures a right angle are complementary angles.
Can a parallelogram always be inscribed in a circle?
No. For example, if one angle measures 100 degrees, and its adjacent angle is 80 degrees, then the opposite angles would be either 200 or 160 degrees, but in order for a quadrilateral to be inscribed in a circle the opposite angles would have to equal 180 degrees. A parallelogram can be inscribed in a circle if it is a rectangle.
