A pentagon need not have any right angles at all, and in fact, a regular pentagon never has any.
A pentagon that's not regular can have any number of right angles less than five.
Whatever they're used for, right angles cannot be acute.
No, pens for horses are usually circular, not built with angles.
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
Yes
This could vary depending on the pen, but it would most likely be a right, circular cone, frequently with the tip removed.

In a acute triangle, all the angles are less than 90 degree's. In a right triangle, one of the angles is 90 degree's, so a triangle cannot be bot acute and right at the same time.

HexagonThere's a trick to this. The x in six is the same with hex.Circle 0 sides.Tri angle 3 sides. Tri = 3Square 4 sides.Pen tagon 5 sides. How many fingers do you hold a pen with? 5.Hex agon 6 sides. Hex... Six....And so on.
with a pencil or pen
no
Yes
10 It depends on the pen.
there is 1 syllable in pen because there is 1 vowel in pen
You can draw a pen many different ways, be creative.
