Proving Parallel Lines
Cards in this deck (10)
- 1What type of lines are m and n?Parallel Lines - Two lines that are always the same distance apart and never touch.
- 2What type of line is line t?Transversal - A line that intersects two or more lines at different points.
- 3What type of angles are m∠1 & 8 and m∠2 & 7?Alternate Exterior Angles - Congruent angles that lie on opposites sides of the transversal, outside the parallel lines.
- 4What type of angles are m∠3 & 6 and m∠4 & 5?Alternate Interior Angles - Congruent angles that lie on opposites side of the transversal, inside the parallel lines.
- 5∠8 = 130: What does ∠4 equal?∠4 = 130
- 6∠3 = 128: What does ∠6 equal?∠6 = 128
- 7∠7 = 66: What does ∠2 equal?∠2 = 66
- 8If ∠H equals 105 and ∠M equals x+112: What's the value of x?x = -7
- 9If ∠I equals 130 and ∠L equals 11x-2: Find the value of x.x = 12
- 10If ∠J equals 60 and ∠O equals 8x-4: Find the value of ∠M.x = 8
∠M = 60
