There are two things missing. How large are the known sides and what are the measures of at least one of the other angles.
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.

3. You need at least three faces. Four faces meeting at a vertex will form a plane (360 deg), 5 or more will make the shape concave (rippled) at that vertex.
The largest angle is opposite the largest side (and so on) - this follows from the Sine rule So GK < GH < KH implies that angle H < angle K < angle G
A right angle is defined as 90 degrees, or pi/2 radians.
There is no polygon with a total angle measure of 200 degrees. The sum of angle measures of a polygon equals to [180 degrees(n - 2)], where n is the number of its sides and n is at least 3.
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.

If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.

Well, honey, if you're talking about a circle, then a quarter of an angle would be 90 degrees. That's because a full circle has 360 degrees, so a quarter would be a nice and neat 90 degrees. So, there you have it, a fourth of an angle measures 90 degrees.
A regular polygon has all the side the same length and the same measures of angels. * * * * * Or measures of angles, even! A concave polygon has at least one angle that is reflex (between 180 and 360 degrees).
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
