A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
Twenty Conjectures in Geometry:Vertical Angle Conjecture: Non-adjacent angles formed by two intersecting lines.Linear Pair Conjecture: Adjacent angles formed by two intersecting lines.Triangle Sum Conjecture: Sum of the measures of the three angles in a triangle.Quadrilateral Sum Conjecture: Sum of the four angles in a convex four-sided figure.Polygon Sum Conjecture: Sum of the angles for any convex polygon.Exterior Angles Conjecture: Sum of exterior angles for any convex polygon.Isosceles Triangle Conjectures: Isosceles triangles have equal base angles.Isosceles Trapezoid Conjecture: Isosceles trapezoids have equal base angles.Midsegment Conjectures: Lengths of midsegments for triangles and trapezoids.Parallel Lines Conjectures: Corresponding, alternate interior, and alternate exterior angles.Parallelogram Conjectures: Side, angle, and diagonal relationships.Rhombus Conjectures: Side, angle, and diagonal relationships.Rectangle Conjectures: Side, angle, and diagonal relationships.Congruent Chord Conjectures: Congruent chords intercept congruent arcs.Chord Bisector Conjecture: The bisector of a chord passes through the center of the circle.Tangents to Circles Conjectures: A tangent to a circle is perpendicular to the radius.Inscribed Angle Conjectures: An inscribed angles has half the measure of intercepted arc.Inscribed Quadrilateral Conjecture: Opposite angles are supplements.The Number "Pi" Conjectures: Circumference and diameter relationship for a circle.Arc Length Conjecture: Formula to calculate the length of an arc on a circle.

We'll get a n number of vertical angles (pairs)
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
Look for any intersecting lines or if they share any same angles to the sides of the triangle.

It is the Cartesian plane created by the French mathematician Rene Descartes
A square...!?!

I think it has the same because it just depends on how to split number they're looking 4
