Definitions
A 2-dimensional shape with length and width.
What is a plane figure?
Every rectangle is a square.
False; Every square is a rectangle but not every rectangle is necessarily a square.
All four of my sides measure 5 cm and I have four right angles.
What is a square?
We have four right angles.
What is a square and rectangle?
Angle A = 90°
Angle B = 90°
Angle C = 90°
Angle D = ?
What is 90°?
A figure that has four right angles with parallel opposite sides and its four sides are all the same length.
What is a square?
The sum of the interior angles of a four-sided figure is 180°.
False, the sum of of the interior angles of a four-sided figure is 360°.
What is a trapezoid?
The sum of our interior angles is 360°.
What is a rectangle, square, parallelogram, rhombus, and trapezoid?
Angle A = 100°
Angle B = 80°
Angle C = 150°
Angle D = ?
What is 30°?
A four sided-figure with four right angles. The opposite sides are the same length and parallel.
What is a rectangle?
All rhombuses, squares, and rectangles are subcategories of parallelograms.
True; Rhombuses, squares, and rectangles have two pairs of parallel sides.
My sides measures 6in, 6in, 10in, 10in and all four of my angles measure 90°
What is a rectangle?
All four sides are equal in length.
What is a square and rhombus?
Angle A = 91°
Angle B = 84°
Angle C = 57°
Angle D = ?
What is 128°?
A four-sided figure with exactly one pair of parallel lines. Its definition does not dictate the measure of the angels or the lengths of the sides.
What is a trapezoid?
A rhombus can be classified as a quadrilateral and a parallelogram.
True. A rhombus has all the characteristics of both a quadrilateral and a parallelogram.
My opposite sides are parallel but all measure 6 inches. My opposite angles measures 110° and my other opposite angles measure 70°.
What is a rhombus?
Our opposite sides are equal in length.
I am a parallelogram. Angle A and C are opposite angles and Angle B and D are opposites?
Angle A = 50°
Angle B = 130°
Angle C = ?
Angle D = ?
What is Angle C = 50° and Angle D = 130°?
A four-sided figure whose opposites sides are parallel and has four sides of equal length. Its opposite angles are equal in measure.
What is a rhombus?
All rhombuses are squares.
False; Rhombuses are not squares because they do not have four right angles. However, all squares are rhombuses because they four sides of equal length and two pairs of parallel sides.
My four sides measure 10, 15, 10, and 15. My opposite angles are equal, but I have no right angles.
What is a parallelogram?
Our opposite angles are equal in measure.
What is a square, rectangle, parallelogram, and rhombus?
The opposite side angles (Angles B and D) are equal in measure.
Angle A = 110°
Angle B = ?
Angle C = 110°
Angle D = ?
What is 70°?
