no
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.
As given 51213 is just a number. However, a triangle with sides 5, 12, & 13, forms a classic Pythagorean right angled triangle.
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
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
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.
7.07 inches
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.
