The one (if any) that is less than 90 degrees.
A scalene triangle could have three acute angles, one right angle and two acute angles, or one obtuse angle and two acute angles.
One acute angle
Adjacent acute angle is not one word. An Adjacent angles are angles that are side by side.
In a right triangle there is only one acute angles.
No it has three acute angles
None. An acute triangle is one in which all angles are acute. An obtuse triangle is one in which one of the angles is obtuse. A right angled triangle is one in which one angle is a right angle (90o)
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.
yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
It can be called obtuse, scalene ( if two acute angles are different ), or isosceles ( if two acute angles are the same ).
An acute angle has one angle.
there are three acute angles in an acute triangle, because there are three corners.
A triangle can only have 3 acute angles because the triangle itself only measures to about 180 degrees. When you seperate the lines that make up the triange, you will notice that it does not pass 90 degrees. Anything below 90 degress, is understood as acute angles. Hope this helps! :)
