What is the number of sides of a triangle multiplied by three?
9 A triangle has three sides times by three = 9
If a polygon has 13 sides how many times does a triangle go into it?
13 triangles will go into a 13-sided polygon.
Prove that the three times the sum of squares of sides of triangle is equal to four times of its median?
Let the triangle be ABC and its medians by AX and BY and CZ. Therefore, since AC=AB, and OP=BD. Therefore, By Triangle Equiangular Property, Triangle ABC simliar to Triangle XYZ Therefore, Three times the sum of the squares of sides of triangle equal to 4 times of its median.:) Hope it helped.
When you triple the length of the sides of a polygon the area is 9 times as large why why not 3 times as large?
Because there are 4 sides of the polygon.
The perimeter of an equilateral figure can be found by multiplying the number of sides by the length of one side?
This is true. A square, which has four equal sides, will have a perimeter equal to four times the length of a single side.An equilateral triangle, which has three equal sides, will have a perimeter equal to three times the length of a single side.Any regular polygon contains all sides of the same length, therefore, the perimeter of a shape with a certain number of sides will be equal to the length of one side multiplied by the number of sides.
How many sides does the polygon have if it has an interior angle which is 3 times the exterior angle?
Providing that it is a regular polygon it will have 8 sides.
Are all regular polygons squares?
Yes. By definition, a regular polygon is a polygon that has all its sides the same length and all its angles equal. A square has all four sides the same length and all four angles equal to 90 degrees. So every square is a regular polygon.
What is the perimeter of an equilateral triangle?
It is the sum of the lengths of the three sides. However, since all three sides are of the same length, the perimeter equals three times the length of any one side.
If an isosceles triangle is a triangle with 2 congruent equal sides if the third side is three times the length of the congruent sides and the perimeter is 75cm find the length of all three sides?
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
What is the area of a 2d shape?
The area of a polygon is calculated using different formula depending on the number of sides of the polygon. The formula for a quadrilateral is length times width, the formula for a circle is pi time the square of the radius, and the formula for a triangle is base times height, divided by two.
If you have the sides of a triangle how do you get the area?
Half The Base, Times The Height Of The Triangle.
How do you work out the area of a scalene triangle?
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.
