3:1 property of parallel lines

Question 1

transversal

Answer 1

is a line that intersects two co planar lines at two distinct points.

Question 2

alternate interior angles

Answer 2

angles on opposite sides of the transversal and inside the parallel lines.

Question 3

same side interior angles

Answer 3

two angles that are on the interior of (between) the two lines and specifically on the same side of the transversal.

Question 4

corresponding angles

Answer 4

the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

Question 5

two column proof

Answer 5

has exactly two columns. One column represents our statements or conclusions and the other lists our reasons.

Question 6

alternate exterior angles

Answer 6

the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal.

Question 7

same side exterior angles

Answer 7

Two angles that are exterior to the parallel lines and on the same side of the transversal line

Question 8

Flow Proof

Answer 8

arrows show the logical connections between the statements

Question 9

obtuse triangle

Answer 9

a triangle in which one of the interior angles measures more than 90° degrees

Question 10

equilateral triangle

Question 11

isosceles triangle

Question 12

acute triangle

Question 13

remote interior angles

Question 14

scalene triangle

Question 15

exterior angle of a polygon

Question 16

quadrangular triangle

Question 17

right angle
