There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
A trapezium has 2 obtuse and 2 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)
three. there are 2 obtuse
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
there are no right angles in a rhombos, but there are 2 obtuse angles and 2 acute angles.
It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.
It can have 0 or 2 right angles, 1 or 2 acute or obtuse angles.
One and the two others are acute angles
A trapezium has 2 obtuse and 2 acute 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.
It has 2 equal opposite acute angles and 2 equal opposite obtuse angles and the 4 angles add up to 360 degrees
In a decagon, which has 10 sides, the sum of its interior angles is calculated using the formula (n-2) × 180°, where n is the number of sides. For a decagon, this results in a total of 1,440°. An obtuse angle is defined as an angle greater than 90°, and in a regular decagon, all interior angles are equal to 144°. Therefore, all 10 angles in a regular decagon are obtuse.
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 rhombus will either have four right angles, or two acute angles and two obtuse angles.
If it is a 'regular' hexagon, then all angles are congruent, and all are obtuse.
Z has two acute angles and two obtuse angles.
The 4 interior angles of a trapezium add up to 360 degrees and if it's an isosceles trapezium it can have 2 equal obtuse angles and 2 equal acute angles
