What is the final step in constructing an angle bisector?

• Draw a line that intersects the angle at a right angle.

• Draw a line that connects the two endpoints of the angle.

• Draw a line that connect the vertex and passes through the intersection of the 2-arcs. This line divides vertex into two equal angles.

• Draw a line that passes through one of the sides of the angle.

Each statement is always true. Select all statements for which the converse is also always true.

• Statement: If 2 angles are vertical, then they are congruent.

  Converse: If 2 angles are congruent, then they are vertical.

• Statement: If 2 lines are perpendicular, then they intersect to form 4 right angles.

  Converse: If 2 lines intersect to form 4 right angles, then they are perpendicular.

• Statement: If a point is equidistant from the 2 endpoints of a segment, then it lies on the perpendicular bisector of the segment.

  Converse: If a point lies on the perpendicular bisector of a segment, then it is equidistant from the 2 endpoints of the segment.

• Statement: In an isosceles triangle, the base angles are congruent.

  Converse: If the base angles of a triangle are congruent, then the triangle is isosceles.

• Statement: If 2 angles form a straight angle, then they are supplementary.

  Converse: If 2 angles are supplementary, then they form a straight angle.
