How do you get perimeters from triangles?
The perimeter of any triangle is the sum of its 3 sides
Why can all five sides figures be made from three triangles?
Because the sum of the sides of three triangles is nine... Placing three triangles together so they all touch effectively removes four of the total number of sides - leaving five.
How many triangles are exist with the following sides 3cm 5cm 9cm?
None because the sum of a triangles smaller sides must be greater than its longest side
How many different triangles can be made if the side lengths are whole numbers and the sum of the sides is 15?
7
Can there be an isosceles triangles that all of its sides add up to 99 but the sides have to be even?
No. The sum of even numbers - however many of them there are - must be even.
How do you divide a polygon into triangles to find the sum of its interior angles?
If a regular polygon has n sides, then the number of triangles in that polygon is n - 2. thus, the sum of its interior angles is equal to (n - 2)180°.
Why was Pythagoras interested in triangles?
Pythagoras was interested in triangles when he found out that for any right angle triangle that when its hypotenuse is squared it is equal to the sum of its two squared sides.
How do you describe triangles?
Triangles are shapes with the following:* three (3) sides * three (3) angles * the sum of 180oSpiritual Health, Physical Health, and Emotional Health.
What is the relationship between the number of triangles and the sum of the angle measures of the polygon?
In a polygon with n sides, the sum of the interior angles is given by (n-2) * 180 degrees. Each triangle has interior angle sum of 180 degrees. Therefore, the number of triangles that can be formed in a polygon is equal to (n-2) * 180 / 180, which simplifies to (n-2). In other words, the number of triangles is two less than the number of sides in the polygon.
How does the pythagorean theorem relate the sides length of a right triangles?
The sum of the squares of the sides adjacent to the right angle equals the square of the side opposite it.
What is similar about all triangles?
they all have three sides, three angles, and the sum of their angles is always 180 degrees.
What do the angles add upto on a 5 sided shape?
Assume each side is a straight line segment. With 3 sides you can make 1 triangle with a sum of interior angles = 180°. With 4 sides you can make 2 triangles with a sum of interior angles = 2 x 180° = 360°. With 5 sides you can make 3 triangles with a sum of interior angles = 3 x 180° = 540°.
