Day 10: Review Unit 3: Coordinate Geometry Did you know that birds need gravity to swallow?

Remember… Skills needed: Length of a line segment 𝐷= 𝑥 2 − 𝑥 1 2 + 𝑦 2 − 𝑦 1 2 Midpoint of a line segment 𝑀= 𝑥 1 + 𝑥 2 2 , 𝑦 1 + 𝑦 2 2 Slope 𝑚= 𝑦 2 − 𝑦 1 𝑥 2 − 𝑥 1 Perpendicular slope = negative reciprocal

Study The Steps For Finding The… Median Altitude Perpendicular bisector Centroid (medians) Circumcentre (perpendicular bisectors) Orthocentre (altitudes) Shortest distance from a point to a line

Test Hints

Matching (Equations) Slope Midpoint Parallel lines/perpendicular lines Distance from origin Distance between any two points Circle Horizontal/vertical line Slope/𝑦-intercept form

Circle Questions Radius from equation, sketch, intercepts Write equation given diameter

Line Segment Questions Length of a line segment Find endpoint given endpoint and midpoint Shortest distance from a point to a line

Medians, Altitudes and Perpendicular Bisectors Find one of them given the triangle

Centroids, Circumcentres, and Orthocentres Explain (in words) how you would find one of them Find one of them
