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. Though there can be ten if the hexagons are concave hexagons.
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.
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.
None. Though there can be ten if the hexagons are concave hexagons.
It has 2 equal opposite acute angles and 2 equal opposite obtuse angles and the 4 angles add up to 360 degrees
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
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
