NO such thing as an 'Acute/Obtuse' Right angle.
Definitely.
ACUTE angles are those less than 90 degrees.
RIGHT angle are 90 degrees exactly.
OBTUSE angle are those which are greater than 90 degrees and less than 180 degrees.
A Straight line has an angle of 180 degrees, when swept from any one point on the straight line.
REFLEX angles are those that are greater 180 degrees and less than 360 degrees. ( NB THe 'outside' of all the above angles).
A rectangle has no acute angles and no obtuse angles. It has 4 right angles.
acute
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
yes an obtuse triangle has two acute angles
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
They are neither, they are all right angles (90 degrees)
A rectangle has no acute angles and no obtuse angles. It has 4 right angles.
A square is a rectangle and a rectangle MEANS 90 DEGREES, so a square also has 90 degrees. :P
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
They are all 90 degrees ( Right angles). The prefix 'recto' is from Latin and means 'right'.
acute
The difference is: 1) the rectangle has all right angles 2)a parallelogram has acute and obtuse angles but not a rectangle
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
no parallelograms can have either obtuse or acute angles. however not a right angle s it makes it a rectangle
A rectangle cannot have any obtuse angles; it contains only right angles. Parallelograms can have two, provided that the others are acute.
A rectangle has 4 interior right angles that add up to 360 degrees
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
