FC: My Geometric Pictures By: Whitney Clark
1: Circle: The set of all points in a plane that are a given distance from a given point in the plane, called the center of the circle.
2: The shape of the tent is a pyramid
3: A pyramid is a solid with the following characteristics: 1. All the faces, except one, intersect at a common point called the vertex. 2. The face that does not intersect at the vertex is called the base. This base is the shape of a square. 3. The faces meeting at the vertex are called lateral faces. These lateral faces are shaped like triangles.
5: Square (left): A parallelogram with four congruent sides and four right angles. Rhombus (above): A parallelogram with four congruent sides. | The purple earings are in the shape of a rhombus.
7: Angle: (left) the union of two rays that have the same endpoint. The five types of angles are zero, acute, right, obtuse, and straight. We will look at pictures of these on later pages. Ray: (right) a one-dimensional figure that consists of one endpoint A, one point B, all of the points on AB, and all points for which B is between them and A.
9: Equilateral Triangle: (top) a triangle with three equal sides Scalene Triangle: (bottom) a triangle with no equilateral sides
11: acute angle: (top left) an angle whose measure is greater than 0 but less than 90 degrees right angle: (top right) an angle whose measure is exactly 90 degrees obtuse angle: (bottom left) an angle whose measure is greater than 90 but less than 180 degrees straight angle: (bottom right) an angle whose measure equals 180 degrees exactly
12: Parallel Lines: (top) two or more coplanar lines that have no points in common or are identical Perpendicular Lines: (bottom) planes in which any two intersecting lines, one in each plane, form a right angle
