All we can tell you is that "perimeter" means "all the way around" ... the lengths of all
the sides when you add them up. The question doesn't give us enough information for
us to return any more help than that. We don't even know how many sides there are
in the figure you're talking about.
A regular quadrilateral is a square. As to the measure, the answer depends on the measure of WHAT? An angle, a side, the diagonal, area, perimeter, etc.
no
a right angle, a obtuse angle, and an acute angle.
Measure it or use trigonometry if the 'included' angle is given.
A traditional kite shape (a point at the top, then widest about 1/3 of the way down, then tapering to another point at the bottom) has one, two or three obtuse (>90 degree) angles. The two angles at the widest point, about 1/3 of the way from the top, are generally obtuse, but don't have to be. The bottom angle is almost never obtuse. The top angle is sometimes obtuse. So if the top angle is obtuse but the side angles are not, a kite shape has one obtuse angle. If the top angle is not, but the side angles are, it has two obtuse angles. If the top and side angles are obtuse it has three.
An obtuse angle.
An obtuse angle
No, this statement is not correct. The side opposite the largest angle is the longest side of a triangle only if the triangle is obtuse. In acute triangles, the side opposite the largest angle is the longest side, and in right triangles, the side opposite the right angle (90 degrees) is the longest side.
An obtuse triangle is a triangle with one angle greater than 90 degrees. Since a perpendicular side is a side that forms a right angle with another side, an obtuse triangle can have 0 perpendicular sides if all its angles are obtuse. However, it can also have 1 perpendicular side if one of its angles is a right angle.
It is an obtuse angled triangle.
Just draw it out. Draw a square with a 3-4-5 right triangle abutting it, laying on its long side with it's short side against the square. The length of the base of the triangle should be about half the length of the square's side. Trace the perimeter of these two objects, and you will get a 5 sided object with: three right edges of a square, with an obtuse angle coming off the side and an acute, reflex angle at the tip of the right triangle.
It is a characteristic of any triangle that the longest side is opposite the largest angle and the shortest side is opposite the smallest angle.
