3. Quadrilaterals Everywhere Can you name the following quadrilaterals?

4. Quadrilaterals Everywhere Quadrilaterals forms either Right Angles, Acute angles, obtuse angels
The Square vertex creates right angles
The parallelogram vertex creates acute angles.
The rhombus vertex creates obtuse angles

5. Quadrilaterals Everywhere Terminology.
A parallelogram has two pairs of parallel sides-opposite sides and angels are congruent
 A square has four right angels and four equal parallel sides
A trapezoid has one pair of parallel sides
 A rhombus has opposite acute angels, opposite obtuse angles and four equal sides
 A rectangle has four right angles and two sets of parallel

6. Quadrilaterals Everywhere Terminology
Congruent objects are equal in size and shape, sides and segments are exact in same length and angles have the same measurement
Perpendicular –are two segments that intersects and create a 90 degree angle
Parallel lines – are lines that does not meet, intersect or touch
