Solid Figures objects that have length, width, and height. Lines & Line Segments Triangles & Polygons Angles Quadrilaterals rectangular prism cube line line segment right angle 90º right triangle (90º) square rectangle parallelogram rhombus trapezoid acute triangle ( < 90º) obtuse triangle (one angle > 90º) equilateral triangle (all sides equal) isosceles triangle (two sides equal) scalene triangle (no sides equal) hexagon (6 sides) acute angle < 90º obtuse angle > 90º Polygon parallel lines intersecting lines ray point pyramid cone cylinder sphere Lines and line segments make up shapes and solid figures. A triangle has three sides. A polygon is any closed plane figure made up of three or more sides. An angle is formed by two rays that share the same end point or vertex. corner or vertex edge vertex 3 cm 3 cm 5 cm 7 cm right angle ray ray face The faces of these solid figures are polygons. The perimeter is the distance around a figure. Volume is the space inside a solid figure. Volume = 8 cubic units Perimeter: Volume: Area: Area = 4 + 4 + 4 = 12 squares Perimeter = 3 + 5 + 3 + 7 = 18 cm © C opyright NewPath Learning.
