How do you find a missing exterior angle of a triangle?
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
Does the measure of an exterior angle at the vertex of a polygon equal the measure of the adjacent interior angle?
The sum of an adjacent interior and its exterior angle will total to 360°. If the angles were to be equal, they would both have to be 180°. An angle of 180° is a straight line. A polygon may be composed of straight lines that intersect at vertices but a straight line has no vertex. That being the case, the answer to your question is "No".
How do we name angles?
Any way you like. Some angles are uniquely identified by their vertex. These can be numbered or allocated letters of the alphabet. Both Greek and Roman alphabets are used although with the Roman alphabet, upper case letters are more common. Where the vertex does not identify the angle uniquely, it may be necessary to use the names of three vertices. For example, the angle XYZ is the angle formed by the rays XY and YZ when they meet at Y.
An angle measuring more than than 90°?
obtuse: greater than 90 degrees right: 90 degrees acute: less than 90 degrees
What is the measure of each base angle of an isosceles triangle if its vertex angle measure 36 degrees and its 2 congruent sides measure 13 units?
If the vertex angle measures 36 degrees, then each base angle is 72 degrees, regardless of the length of the congruent sides. They may be the length of a DNA strand, a 57 Chevy, or the distance to the Andromeda Galaxy. It doesn't matter. The base angles are still 72 degrees.
How do you bisect a reflex angle?
The method is exactly the same as for bisecting any other angle. You may find it easier to bisect the "other side" of the reflex angle, which will be at most obtuse and then extent the bisector through the vertex to the other side.The method is exactly the same as for bisecting any other angle.

What are three ways to name an angle?
Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.

What type of polygon has at least one angle greater than 180ο?
Any polygon with more than three sides may have an angle greater than 180 degrees.

What is the type of angle a triangle is?
A triangle is not an angle. In fact, every triangle is composed of three angles. One of them but not more may be a right angle, or one of them but not more may be an obtuse angle, but one or more of them must always be acute.
Are all complementary angles adjacent?
No, because a complamentary angle just equals 90 degrees. An adjacent angle has a vertex and a common ray the same. If you have two angles that are not touching they cannot be adjacent because they dont have a same ray, but they may have a same vertex. If the two angles add up to 90 degrees they are complimentary and dont have to have anything the same. Hope this helps! If it is confusing look up what an adjacent angle is, then look up what a complamentary angle is! :)
What is 'vertex' in English?
An English equivalent of the Latin noun 'vertex' is whirl, eddy. It also may be crown of the head. Or it may be summit.
How many right angles in an isoscles trinagles?
A triangle may or may not have one right angle, but it can never have more than one. A triangle with one right angle is isosceles only if each of the other two angles is 45 degrees.
