I think it is either a right triangle, square, pentagon, or rectangle.
Sarah said that triangles have one pair of perpendicular lines and acute and obtuse triangles each have one pair of parallel lines.
a right angled triangle
A plus sign (+) would be a pair of perpendicular line segments.
The lines that meet at right angles are perpendicular to each other.
Some intersecting lines are perpendicular lines.Take any old pair of intersecting lines. If the angles at the intersectionhappen to be 90 degree angles, then the lines are perpendicular lines.
No because perpendicular goes up and down
Trapizium
a pair of intersecting lines that are perpendicular
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
a triangle, pentagon and that's all i can think of * * * * * A right angled triangle has a pair of perpendicular lines! Likewise, a pentagon can have a pair. A circle, ellipse etc do not.
A right angle triangle
A right-angle triangle.
a right angled triangle
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
Lines that intersect at 90 degrees are perpendicular lines
No parallel lines but a right angle triangle has perpendicular lines.
A plus sign (+) would be a pair of perpendicular line segments.
shape no pairs of perpendicular sides
