An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
NO they are not.
It has 3 interior acute angles 2 of which are equal in size
Any polygon can contain acute interior angles.
Not always because one of the interior angles could be obtuse.
Although a triangle must have at least two acute interior angles, a square has four interior right angles and no acute angles. And as regular polygons have increasing numbers of sides, their interior angles get larger.
No because it has 2 equal interior acute angles and 2 equal interior obtuse angles but its 4 sides are equal in length
Only if it is a rectangle otherwise it has equal opposite acute angles and equal opposite obtuse angles and the 4 interior angles add up to 360 degrees
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
A regular six-sided hexagon has no interior acute angles, but it does have six interior obtuse angles, each measuring 120 degrees
No. If all 5 angles were acute, then they would add up to less than (5 x 90°) = 450°. But the sum of the interior angles of a pentagon is always 540° .
There are no acute angles in a rectangle which has 4 equal interior right angles
A triangle has only 3 interior angles. It may have either 3 acute internal angles or 2 acute and 1 obtuse internal angles.
Sometimes it is if its 3 interior angles are acute angles and add up to 180 degrees
Yes. In fact, there has to be at least two. Acute angles are angles less than 90 degrees.
