31 DAY 6 2.8 CLASSIFYING SHAPES ON A COORDINATE PLANE MPM 2D Coordinates and Geometry: Where Shapes Meet Symbols

32 2.8 Classifying Shapes on a Coordinate Plane Quadrilaterals four sided polygons Parallelogram both pairs of opposite sides are parallel

33 2.8 Classifying Shapes on a Coordinate Plane Rectangle a parallelogram in which the interior angles are all right angles

34 2.8 Classifying Shapes on a Coordinate Plane Square a rectangle with all sides equal length

35 2.8 Classifying Shapes on a Coordinate Plane Rhombus a parallelogram with all sides equal length

36 2.8 Classifying Shapes on a Coordinate Plane If you know the vertices of a quadrilateral, you can classify the quadrilateral by finding the length and slopes of each side. If you know the vertices of a triangle, you can use the lengths of the sides to determine whether the triangle is scalene, isosceles or equilateral. The slopes of the sides can be used to determine if it is a right triangle.

37 2.8 Classifying Shapes on a Coordinate Plane

38 Example 2 – Read page 179, example 2. To solve, find the slope and length of each side. If it is truly a rectangle, opposite sides will be parallel and adjacent sides will be perpendicular.

39 2.8 Classifying Shapes on a Coordinate Plane End of Day 6 HW Pg. 182# 2, 5, 8, 14

40 DAY 7 2.10 USING THE POINT OF INTERSECTION TO SOLVE PROBLEMS MPM 2D Coordinates and Geometry: Where Shapes Meet Symbols

41 2.10 Using the Point of Intersection to solve problems The centroid, circumcentre, and orthocentre can be located on a triangle on a coordinate grid if the vertices are known. Centroid Where the three medians meet; also known as the centre of mass. Can be found by determining the equations of two median lines, then finding their intersection point.

42 2.10 Using the Point of Intersection to solve problems Altitude The line segment representing the height of a polygon, drawn from the vertex of the polygon perpendicular to the opposite side

43 2.10 Using the Point of Intersection to solve problems Circumcentre The centre of the circle that passes through all three vertices of a triangle. Can be found by finding the equations of the perpendicular bisectors of two sides, then finding their intersection point.

44 2.10 Point of Intersection Orthocentre The point where the three altitudes of a triangle meet. Can be found by determining the equations of two altitude lines, then finding their intersection point.
