A 90 degree angle and 2 acute angles will form a right angle triangle.
The given vertices when plotted on graph paper will form an isosceles triangle with 2 equal exterior angles of 123.69 degrees and a 3rd exterior angle of 112.62 degrees with an area of 78 square units
A triangle has 3 closed sides A triangle has 3 interior angles that add up to 180 degrees A triangle has 3 exterior angles that add up to 360 degrees A triangle has a perimeter which is the sum of its 3 sides A triangle will tessellate leaving no gaps or over laps A triangle's 3 angles put together will form a straight line
Because angles on a straight line will always add up to 180 degrees
Any three angles that sum to 180 can form a triangle.

If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.

Interior and adjacent exterior angles form a straight line so exterior angle = 180 - interior angle. If you are satisfied with this reply please consider awarding a Recommended Point to the responder.
In a triangle, if an angle is adjacent (shares a side) and supplementary (adds up to 180 degrees) to one of the interior angles, it means that the two angles together form a straight line. In other words, the three angles of the triangle add up to 180 degrees.
a triangle always forms two angles?
No, intersecting lines form four pairs of supplementary angles
yes, intersecting lines form two pairs of congruent angles
