A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two. When two lines intersect they form two pairs of opposite angles, A + C and B + When a transversal intersects with two parallel lines eight angles are produced. Two pairs of points are selected on two sides of a triangle. The task is to construct two points on the third side such that they produce two pairs of parallel lines.

## quadrilateral

One of the definitions of a parallelogram is 2 pairs of parallel sides. Therefore, any parallelogram MUST have 2 pairs of parallel sides. Let's start by examining the group of quadrilaterals that have two pairs of parallel sides. These quadrilaterals are called parallelograms They take a variety of. In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a.

I am assuming (perhaps unjustifiably) that when you say “two pairs of parallel sides” you are talking of a figure with no other sides than those. Parallel Lines, and Pairs of Angles. Parallel Lines. Lines are parallel if they are always the same distance apart (called equidistant), and will never meet. A, B. square, I have four equal sides, two pairs of parallel lines, and four right angles. trapezoid, I am a quadrilateral with one pair of parallel lines, two acute.

## how many pairs of parallel sides does a trapezoid have

Parallelogram: A quadrilateral that has two pairs of parallel sides. Rhombus: A quadrilateral with four congruent sides; a rhombus is both a kite and a. A rhombus has four sides of equal lengths. It has two pairs of equal angles. The opposite sides are parallel. The diagonals bisect each other at right angles. Symmetry: Two lines, rotational order 2. Parallelogram. properties of a parallelogram. Sides: Two pairs of opposite sides equal and parallel. Symmetry: No lines. Page and Other Contents: Vertical Pairs of Angles: Adjacent Supplementary Angles: Names At each of the parallel lines, there are two pairs of vertical angle. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A quadrilateral with one pair of parallel sides is a trapezoid. If it has two pairs of parallel sides it is a parallelogram, but parallelograms are also trapezoids in the. The diagram shows two pairs of parallel lines. The measure of angle A is °. The measure of angle C is _____ Get the answers you need. Name two pairs of parallel lines in the figure. From Figure, name All pairs of parallel lines. all pairs of intersecting lines. lines of whose point In Fig A,B,C . Or the polygon could have two pairs of parallel sides, like this square and Or this regular octagon shows that you could have four pairs of parallel sides. Can you name these quadrilaterals? a) All sides are the same length, opposite sides are parallel, angles are not 90 degrees. b) Two pairs of touching sides are .
