Right Angle
The right angle is formed by the intersection of the triangle's "legs".
Straight ones
The two sides in a right triangle that form the right angle.
They are the two shorter sides which meet to form the right angle.
Two lines that form a right angle are Perpendicular. This can be show by an upside down T.
When two lines intersect to form a right angle they are called perpendicular.
Intersecting two perpendicular lines will form right angles.
Right Angle
that would be a right angle.
a quadrilateral where each angle is a right angle
Roads don't always form an acute angle, they can form a right angle. If you are really picky, you might say that they can never form a perfect right angle, so two of the angles formed must be acute (and the other two obtuse).
The right angle is formed by the intersection of the triangle's "legs".
the lines are perpendicular, which basically means the two lines intersecting form a right angle
They are the "legs" of the triangle.
