The longest side is always opposite the right angle so the sides of the right angle are 3 and 4 units.

Yes because the given dimensions comply with Pythagoras; theorem for a right angle triangle.

A pentagon has 5 sides

Any regular polugon with 5 or more sides. Many irregular polygons with 5 or more sides will also meet the requirements.

It could be an isosceles triangle that is not right angles; an isosceles trapezium, a trapezium where one of the parallel sides is equal to one of the sloped sides; any irregular polygon with 5 or more sides where two are equal, and no right angles.

The sum of the squares of the sides that include the right angle must equal the square of the hypotenuse (Pythagoras). To construct a right angle triangle the three sides can have proportions of 3, 4 and 5 relative to one-another. Example: 3 cm, 4 cm and 5 cm.

The longest side is always opposite the right angle so the sides of the right angle are 3 and 4 units.

A regular pentagon

3 : 4 : 5

It's not possible to have a right angle triangle with sides of equal length. The sides on a right angle triangle are always in the ratio 3:4:5.

You can use Pythagoras theorem to lay out a right angle. Often referred to as 3:4:5 If the hypotenuse is 5 units and the other sides are 3 and 4 units respectively then it will be a right angle.

A figure with five sides is a pentagon.

Yes because the given dimensions comply with Pythagoras; theorem for a right angle triangle.

A pentagon has 5 sides

Any regular polugon with 5 or more sides. Many irregular polygons with 5 or more sides will also meet the requirements.

Any convex figure can have an exterior angle measuring 72 degrees. If you consider only regular polygons, then it wuld be a polygon with 360/72 = 5 sides, that is, a pentagon.
