Quadrilaterals and Triangles Part One: Rectangles, Squares
Quadrilaterals RectanglesSquares 1. Draw It 2. Tell me about the sides (parallel, perpendicular, congruent) 3. Tell me about the angles (acute, obtuse, right)
Perimeter and area Perimeter: –Distance around a shape –Units are linear, such as inches or centimeters. Area: –Space in a shape –Units are square units, such as square inches or square centimeters.
Formulas for squares, rectangles, and parallelograms Formula for finding perimeter P = 2(base + height) Formula for finding area A = (b)(h)
Which are 4-sided polygons? Quadrilaterals Triangles Rectangles Pentagons Squares Rhombus Pyramid Hexagons Prism Kite Circles Trapezoid Cubes Octagon Parallelogram Cylinder
Part 2: Triangles How are they related to parallelograms?
Can you split these shapes in half by drawing a diagonal line?
How is a triangle different?
How do we find perimeter and area?
Formula Area of parallelograms, rhombus, rectangle, square = (base)(height) Area of triangles = (base)(height)
What if it is not a right triangle? Find the right ( ) Altitude.
Let’s review our shapes….
Circle – Formulas Radius of the circle is generally denoted by letter R. Diameter of the circle D = 2 × R Circumference of the circle C = 2 × × R (
