Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). These properties concern its sides, angles, and diagonals. i looked at videos and still don't understand. The basis to respond this question are: 1) Perpedicular lines form a 90° angle between them. A parallelogram with a right angle and opposites sides that are congruent. • Based on the information in the diagram, can you prove that the figure is a parallelogram? All 4 sides are congruent. Since the square is the last one in the hierarchy, therefore, it must have all the properties of a parallelogram, rectangle, and rhombus. A The diagonals of a rectangle divide the rectangle into four nonoverlapping isosceles triangles. Which statement describes a parallelogram that must be a square? Determine whether each quadrilateral must be a parallelogram. 14. The distance formula given above can be written as: This is precisely the Pythagorean Theorem if we make the substitutions: , and .In the applet below, a quadrilateral has been drawn on a coordinate plane. These properties concern its sides, angles, and diagonals. Rhombus It is a square C. It is a quadrilateral D. It is a rectangle E. It is a kite. Consecutive angles are supplementary (A + D = 180°). Parallelogram formulas – Area and perimeter of a parallelogram. A. (In addition, the square is a special case or type of both the rectangle and the rhombus.) Calculations include side lengths, corner angles, diagonals, height, perimeter and area of parallelograms.
