A heat is the collection of every points whosecoordinates are remedies to a straight equation in two unknowns.7. Two lines are parallel if theirslopes are the same.8. 2 lines are perpendicularif your slopes are negative reciprocals of every other.9. Provided a line and also a point, the suggest wherethe line v the given point perpendicular come the offered lineintersects the provided line is called the foot of the point inthe line.10. A circle has a center and all ofthe clues on the circle are the exact same distance indigenous the center. Thisdistance is dubbed the radius the the circle.11. A chord the a circle is a linesegment whose endpoints room on the circle.12. A diameter of a one is a chord which goes with the center of the circle.13. A radius that a circle is a line segment i m sorry goes from the facility of a circle come a allude on the circle. 14. A line that meets a one in exactlyone suggest is dubbed a tangent come the circle.15. If A, B, and C are points on acircle, climate angle BAC is referred to as an inscribed angle.16. If O is the center of a circle andB and C space points top top the circle, climate angle BOC is called acentral angle.17. A parallel is a foursided number where opposing sides space parallel.18. A rectangle is a 4 sidedfigure wherein all four angles are ideal angles.19. A rhombus is a four sided figurewhere all 4 sides have actually the very same length.20. A tirangle is one isoscelestriangle if 2 of the sides have actually the very same length.21. A triangle is an equilateraltriangle if all 3 sides have the very same length.22. A mean of a triangle is a linesegment native one verted come the midpoint of the opposite side.23. One altitude that a triangle is aline segment indigenous one peak perpendicular come the the opposite side24. The allude where the perpendicularbisectors of the three sides the a triangle accomplish is dubbed thecircumcenter the the triangle.25. The circle i m sorry goes through allthree points of a one is referred to as the circumscribed one orcircumcircle.26. The point where the three anglebisectors of a triangle accomplish is called the incenter that thetriangle.27. The circle come which all three sides ofa triangle room tangent is called the inscribed one orincircle.28. The suggest where the three medians of atriangle accomplish is called its centroid or facility ofgravity.29.The point where the 3 altitudesof a triangle satisfy is called the orthocenter that the triangle.30. The Euler heat of a trianglegoes with the circumcenter, thecentroid, and theorthocenter.31. The 9 allude circle is focused at themidpoint that the Euler line and goes throughthe midpoints of the 3 sides, the feet the thealtitudes, and also the midpoints the the heat segments in between theorthocenter and the vertices that thetriangle.32.
