Is it true if a polygon has odd number of angles the angles cannot be congruent?
No, it is not true that a polygon with an odd number of angles cannot have congruent angles. A polygon can have an odd number of angles and still have some or all of them be congruent. For example, a regular pentagon has five angles that are all congruent, and a polygon with an odd number of sides can also have pairs of congruent angles.
What polygon has two pairs of parallel sides but doesn't have four congruent angles?
A parallelogram.
What has 2 pairs of opposite congruent angles?
It could be a polygon with 4, 6, 8, etc vertices.
What is a quadrilateral with four congruent angles and two pairs of congruent sides called?
a rectangle
Mathematical definition of a square?
A four-sided polygon with congruent sides and angles, and two pairs of parallel sides.
How do a irregular polygon look like?
An irregular polygon is a plane (2-dimensional) shape which is bounded by straight lines that meet in pairs. If all the sides are congruent AND all the angles are congruent then the polygon is regular: otherwise it is irregular.
What is a four-sided polygon with two pairs of congruent sides and the congruent sides are adjacent?
A polygon.
Are both pairs of opposite angles are congruent in a parrallelogram?
Yes, both pairs of opposite angles in a parallelogram are congruent.
Are all angles in a trapezoid congruent?
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
Are there two congruent angles in a rhombus?
two pairs of congruent angles in a rhombus
What angle is two pairs of opposite and congruent angles formed by intersecting lines?
Such angles are called vertically opposite angles.
A quadrilateral with 4 congruent angles and 2 pairs of congruent sides?
A rectangle has 4 congruent angles. 90 degrees. It is also a parallelogram, 2 pairs of congruent sides.
