What is the definition of a midsegment in a triangle?

• A line segment that connects the midpoints of two sides of the triangle.

• A line segment that connects the vertices of the triangle

• A line segment that connects the midpoints of all three sides of the triangle

• A line segment that connects the midpoints of two angles of the triangle

Define the angle bisector of a triangle.

• A line that divides an angle into two equal angles

• A line that divides a triangle into two right angles

• A line that divides a triangle into two unequal angles
