What is the difference between an acute triangle and an obtuse triangle?
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
How many acute angles in a decagon?
A regular 10 sided decagon has 10 exterior acute angles each measuring 36 degrees It has no interior acute angles because each interior angle measure 144 degrees
How many acute angles does a trapezoid have?
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.
Are vertex angles always acute?
NO they are not.
What does a acute isoscesles triangle look like?
It has 3 interior acute angles 2 of which are equal in size
What contains acute interior angles?
Any polygon can contain acute interior angles.
Does all angles of a scalene triangles are acute angles?
Not always because one of the interior angles could be obtuse.
Is there a minimum number of acute interior angles that any polygon can have?
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.
Is a rhombus always equilangular?
No because it has 2 equal interior acute angles and 2 equal interior obtuse angles but its 4 sides are equal in length
What is the difference between an acute triangle and an obtuse triangle?
An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles
Are the interior angles of a parallelogram always congruent?
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
How many acute angles does a hexagon have?
A regular six-sided hexagon has no interior acute angles, but it does have six interior obtuse angles, each measuring 120 degrees
How many acute angle are in a rectangle?
There are no acute angles in a rectangle which has 4 equal interior right angles
Is a triange acute?
Sometimes it is if its 3 interior angles are acute angles and add up to 180 degrees
Does a triangle have 6 obtuse interior angles?
A triangle has only 3 interior angles. It may have either 3 acute internal angles or 2 acute and 1 obtuse internal angles.
Is it possible for a pentagon to have all acute angles?
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° .
Can two interior angles of a triangle have acute angles?
Yes. In fact, there has to be at least two. Acute angles are angles less than 90 degrees.
