Angles are used in designing and creating structurally sound buildings. It would be pointless if you had a flat roof, wouldn't it?
Easiest that way to get them to carry their own weight, and the weight of the roof.
An irregular pentagon such as a child's silhouette of a house: a rectangle shape (open at the top) forming the body of the house, with a triangular roof on of the rectangle. The vertical line through the apex of the roof is the line of symmetry. The two walls, and the two roof lines are the two sets of equal sides. The two right angles at the base are the one set of matching angles.
It is an irregular pentagon - a bit like a child's silhouette of a house with a pitched roof.
A regular pentagon has 5 equal endless and no equal sides. However if you draw a pentagon like simple house with a square below and a trainable on top for the roof, then you get one pair of parallel sides (the walls) but it will always have 5 angles.
Lots of possibilities, but a simple one is to imagine a child's drawing of a house. This will usually consist of a square (or rectangular) "house" part with a triangular roof on top. If the roof is steep enough, it will have an acute angle at the top. The two base angles (sides of the house) will be 90 deg and the two angles where the walls meet the roof will be obtuse.
On your roof
use an angle finder
It could look like a child's drawing of a house: a rectangular shape with a triangular roof on top.The vertical sides of the rectangle, and the sloped sides of the roof would be the two congruent pairs of sides.The angles at the base of the rectangle and at the base of the roof would be the two pairs of congruent angles.It could look like a child's drawing of a house: a rectangular shape with a triangular roof on top.The vertical sides of the rectangle, and the sloped sides of the roof would be the two congruent pairs of sides.The angles at the base of the rectangle and at the base of the roof would be the two pairs of congruent angles.It could look like a child's drawing of a house: a rectangular shape with a triangular roof on top.The vertical sides of the rectangle, and the sloped sides of the roof would be the two congruent pairs of sides.The angles at the base of the rectangle and at the base of the roof would be the two pairs of congruent angles.It could look like a child's drawing of a house: a rectangular shape with a triangular roof on top.The vertical sides of the rectangle, and the sloped sides of the roof would be the two congruent pairs of sides.The angles at the base of the rectangle and at the base of the roof would be the two pairs of congruent angles.
The Temple of Vesta in Rome was about 14 meters (46 feet) in height. It was a small circular temple with a cylindrical cella and a conical roof.
a pentagon with two adjacent right angles
It depends on the prism. A prism that has a regular pentagon as base but is not a right prism has no right angles. At the other extreme, consider a right prism whose bases are pentagons that resemble a child's drawing of a house (square with a triangle roof). If the angles of the roof triangle are 90-45-45, the prism will have 22 right angles.

A scalene specifies that no two sides and no two angles are equal. A right triangle has one side that is a right or 90 degree angle. A scalene triangle can be a right triangle {a 3-4-5 right triangle or a 30°-60°-90° right triangle, for example}. A scalene triangle can also be an acute or obtuse triangle. Note this: there is only one case of a right triangle, which is non-scalene. This is the isosceles right triangle with angles 45°, 45° & 90°, and sides sqrt(2), 1 & 1. All other right triangles are scalene. The terms scalene, isosceles, and equilateral refer to how the side lengths are related to each other. The terms right, acute and obtuse refer to angles, specifically the largest angle: obtuse - the largest angle is greater than 90°; right - the largest angle equals 90°; acute - the largest angle is less than 90°. The terms referring to angles are not necessarily mutually exclusive with the terms, which refer to side lengths (except for equilateral). So you can have an isosceles obtuse (a shallow pitched roof), or isosceles right (example above), or isosceles acute (a very steep pitched roof).

The easiest roof to build would be a lean to roof. There are no angles, ridges or gables to deal with.Simply put, it is a flat roof with a slight pitch so water can run off it.Also, many different kinds of materials can be used to actually put on the roof, from pitch and tar to shingles.
