  • by two parallel lines cut by a transversal and the relationship between the slopes of parallel lines. • Students should walk in with the room already prepared for the lesson. As many coordinate planes as possible should be prepared with the two parallel lines and the transversal included (second, so that they can be removed).

    • r = 1 + cos(π/2) = 1, so we graph the point at distance 1 from the origin along the positive y-axis, which is at an angle of π/2 from the positive x-axis. When θ = 7π/4, r = 1 + cos(7π/4) = 1 + √ 2/2 ≈ 1.71, and the corresponding point appears in the fourth quadrant. This illustrates one of the potential benefits of using polar ...

  • Angle Pairs Game - Beat the Clock Aim : The purpose of this game is to recognise the equal and supplementary angles formed when a transversal cuts a pair of parallel lines. It also aims at learning the correct names for the pairs of angles.
  • Intersecting lines cross each other. Parallel lines never cross each other - they stay the same distance apart. You can use intersecting and parallel lines to work out the angles in a triangle.
Angles 8 and 2 and angles 3 and 7 are on opposite sides of the transversal and between (interior) the parallel lines. We call these angles alternate interior angles. Angles 1 and 5 and angles 4 and 6 are on opposite sides of the transversal and above and below (exterior to) the parallel lines. We call these angles alternate exterior angles.

Parallel Lines Cut by a Transversal Practice and Problem Solving: C At the right is a map of Littleton. North Street, Center Street, and South Street are parallel. Use the description to complete Exercises 1–2. 1. Avenue A is perpendicular to North Street. What is the relationship between Avenue A and South Street? Explain your reasoning.
Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
