A triangle can have one angle made up of perpendicular lines. That would be called a right triangle. A triangle cannot have more than one angle made up of perpendicular lines however. To see why, remember that an angle created by two perpendicular lines is 90 degrees and a triangle is made up of three angles that sum to 180 degrees. If two angles were 90 degrees the third angle would have to be 0 degrees, in which case the shape is no longer a triangle.
No. a equilateral triangle does not have perpendicular sides.
An equilateral triangle doesn't have any perpendicular sides on it.
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
The perpendicular sides of a right triangle are its legs. The remaining side is the hypotenuse.
no a equilateral triangle does not have any perpendicular sides because the lines are joined together.
No. a equilateral triangle does not have perpendicular sides.
No. a equilateral triangle does not have perpendicular sides.
No, not in general. Only a right triangle has two sides which are perpendicular.
An equilateral triangle doesn't have any perpendicular sides on it.
a triangle with 2 sides
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
The perpendicular sides of a right triangle are its legs. The remaining side is the hypotenuse.
No triangle can have parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees
no a equilateral triangle does not have any perpendicular sides because the lines are joined together.
The perpendicular adjacent sides in the triangle would be 3 sides. It is the basically horizonstal line next to a vertical line(perpendicular) if it was parallel adjacent then only two side of triangle /\ <-- parallel
No but a right angle triangle has perpendicular sides and an hypotenuse.
No
