### If two triangles have three pairs of congruent angles the the triangle is congruent?

Yes they are. Or they could have three pairs of congruent sides,
or they could have one pair of congruent angles and two pairs of
sides. As far as a triangle goes, if you have at least three pairs
of congruent sides or angles they are congruent.
This answer is wrong. The triangles are only similar.
For congruent trisngles we have the following theorems = Side -
side - side,
Side - Angle - side , Angle - angle - side, Right triangle -
hypotenuse - side.

### What is a Quadrilateral with two sets of parallel sides?

It is a parallelogram
If one of the angles is a right angle (then they all are) and
the quadrilateral is a rectangle.
If both pairs of sides are equal in length (but none of the
angles is a right angle) the quadrilateral is a rhombus.
If the sides are equal and one of the angles is a right angle,
the quadrilateral is a square.

### What are the different pairs of angles?

Pairs of Angles
1.Complementary Angles
-are two angles together complete a right angle.
*The two angles need not be to be adjacent.
-to find the complement angle subtract the given angle from
90°.
Ex: Give the complement of 65°.
1. 90°-65° =25° (25+ 65=90)
2. 90°-70° =20° (20+ 70=90)
2.Supplementary Angles
-are two angles whose measurements are equal to 180°.
*The angles not also be adjacent.
-To find the supplement angle, subtract the given angle from
180°.
Ex:
1. Give the supplement of 130°.
180°-130°=50°
3.Adjacent Angles
-two angles with a common side and the same vertex.
4.Vertical angles
-are opposite angles formed two intersecting lines.
They have a common vertex but no common side.
