No. In fact, it is impossible for a figure to have two 90 degree angles and three line segments, or it would look like this. ________ | | | _______ Therefore if it looked like that, it wouldn't be a CLOSED shape of any kind. (The total of the three angles in a triangle is 180 degrees. The would be no 3rd angle.)
Perpendicular lines are ones that make right angles when they meet. For instance the letters T H E and L are all made of perpendicular line segments.
Since I can't attach illustrations here (can I?), I can describe one. If two congruent and parallel triangles have vertices joined by line segments, the line segments described will mark the boundaries of a solid.
A perpendicular line is two lines that look like a plus +. If they're not perpendicular, they don't cross with 90 degree angles.
There has been many different answers to this question, but the proper answer is two right angles. even though it doesn't look like!
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.

Line segments that do not intersect are parallel lines
Segments of equal length are called congruent segments. You can identify them by congruency marks. congruency marks look like this on your line: ---l-----------l---
A polygon is a plane figure that is closed with straight line segments.
Perpendicular lines are ones that make right angles when they meet. For instance the letters T H E and L are all made of perpendicular line segments.
It is a straight line that intersects another straight line at right angles or 90 degrees.

Two trapezoids
A perpendicular line is a straight line that intersects another straight line at right angles or 90 degrees on all four sides.
A perpendicular line is two lines that look like a plus +. If they're not perpendicular, they don't cross with 90 degree angles.
