1- 2- 3- For exercice 1-17 you have to write the correct word in each rectangle. >A is the most basic building block of geometry. > A has length and width, but no thickness. >A is a straight, continuous arrangement of infinitely many points. 4- 5- 6- A consists of two points called the of the segment and all the points between them that are collinear with the two points. means on the same line. means on the same plane. 9- 10- 8- 7- The two rays are the of the angle. An is formed by two rays that share a common endpoint. A begins at a point and extends infinitely in one direction. The common endpoint of the two rays is the of the angle. 11- 12- The geometry tool you use to measure an angle is a . The is the smallest amount of rotation about the vertex from one ray to the other, measured in . 13- 14- A of a circle is a geometric line segment whose endpoints both lie on the circumference of the circle. A is the set of all points in a plane at a given distance from a given point. The given distance is called the and the given point is called the . 16- 15- 17- A is an arc of a circle that is smaller than a semicircle. the of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the boundary of the circle. A is an arc of a circle that is larger than a semicircle. 19- 18- For exercise 18-30 you have to put (True) or (False) in each rectangle. Do not put T or F. If you do, you get the question wrong. The measure of Complementary angles is 180. The measure of suplementary angles is 90. ∘ ∘ 21- 22- 20- The measure of the angle 'b' is 50. The measure of the angle 'c' is 50. The measure of the angle 'a' is 50. b 130 c ∘ a ∘ ∘ ∘ 24- 23- 25- The angle 2 are corresponding angles with the angle 6. The angle 3 are alternate interior with the angle 5. The angle 1 are alternate exterior with the angle 8. 7 5 8 3 6 1 4 2 27- 28- 29- 30- 26- Perpendicular lines form angles that measure 180. The right triangles have exactly one angle that its measure is 90. Point, line, and plane are the three undefined terms in Geometry. An Isoceles triangle has exactly two angles that their measures add to 90. The parallel lines never intersect. ∘ ∘ ∘ |
