A right angle triangle has one 90 true or false?
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
A triangle can have two right angles true or false?
false
The base angles of an isosceles trapezoid are not congruent true or false?
False
The sum of the angles of a parallelogram is 180 true or false?
False, the sum of the angles in a parallelogram is 360 degrees.
True or false Similar polygons have congruent sides and congruent angles?
False. The angles will be congruent, but the sides not so.
Do all quadrilaterals have at lease 1 right angle true or false?
no,all quadrilaterals have 4 right angles
Do all quadrilaterals have at least one right angle true or false?
False because it depends on what type of a 4 sided quadrilateral it as for example a square has 4 right angles whereas rhombus has no corner right angles.
Do quadrilaterals have at least one right angle true or false?
yes
A right angle triangle has one 90 true or false?
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
A quadrilateral with one right angle must be a rectangle true or false?
FALSE because a rectangle has 4 right angles.
A triangle can have two right angles true or false?
false
Are all right angles similar true or false?
true:right angles are similar
Perpendicular lines do not meet to form right angles... True or false?
False.
A rhombus is a square true or false?
False. Every rhombus is a parallelogram, but not every rhombus is a square. Only those that have right angles are squares. Every rhombus is a parallelogram because its diagonal lines are perpendicular, and they bisect an interior angle.
All rectangles are quadrilaterals true or false?
true
What is never true about a quadrilaterals?
a quadrilateral can contain 2 right angles,one obtuse and one acute angle.
True or false Perpendicular lines form straight angles?
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
