if DC = 10 What is the measure of angle ABD?
All you have to remember for this question is that opposite angles in a parallelogram are equal. So if you want to find another angle which is 57, just look at the angle directly opposite.
10!
The angles are supplementary if they have a sum of 180 degrees.
216 is the angel of g
67 degrees
Complement of a given angle = (90 - given angle) Supplement of a given angle = (180 - given angle)
The sum of the two angles is 360. So angle ABC = 120 degrees.

No, a figure and its reflection image are congruent. It is like our reflections in a mirror. Hope I answered your question!
30 is the answer A+ student raynaray

An angle with 30 degrees is an acute angle.
Very rarely.
Depends from the given information. For example, if it is given the measure of the angle base θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/cos θ If it is given the measure of the angle base θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/sin θ If it is given the measure of the vertex angle θ, and the length of the base b, the sum of the sides a of the isosceles triangle equals to 2a = b/sin θ/2 If it is given the measure of the vertex angle θ, and the length of the height h, the sum of the sides a of the isosceles triangle equals to 2a = 2h/cos θ/2 If it is given the length measures of the base b and the height h, the sum of the sides a of the isosceles triangle equals to 2a = √(h4 + b2) (from the Pythagorean theorem)
a right angle equals 90 degrees.
