Well, strictly and technically, I guess you can, although it's a weird triangle.
Its angles are 0, 0, and 180 degrees, its height and area are both zero, and
to look at it you'd never know it's a triangle unless someone tells you, because
it looks just like a 25-inch line segment.
the area of a triangle is half that of a rectangle made using two of those triangles.
P = a + b + cyou just add the sides together.Just add up the three sides of the triangle.
Oh, dude, let me break it down for you. So, for a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 20 + 20 is 40, which is equal to the third side length. So, no triangle here, just a straight line. Like, nice try, but not today.
because you can't just change one of the angles or one of the side lengths without breaking the triangle. All the angles and sides re-inforce each other. Image a square made out of sticks that are attached loosely at the corners. You can squish two of the corners together to make a diamond shape, and you haven't changed the length of the sides. But if you have a triangle made out of sticks, you can't change it's shape without destroying it.
Pi
To see if three lengths can be made into a triangle:Add together the two shorter lengths;if this sum is greater than the remaining length, then a triangle can be made;otherwise the sum is less than or equal to the remaining length and a triangle cannot be made.examples:3, 4, 53 + 4 = 7 > 5 ⇒ is a triangle 5, 5, 85 + 5 = 10 > 8 ⇒ is a triangle 12, 30, 1812 + 18 = 30 ≤ 30 ⇒ is not a triangle 12, 35, 1812 + 18 = 30 ≤ 35 ⇒ is not a triangle
The standard length for a pencil is about 7 inches.
Most racquets made by the brand names and used by professionals (like Babolat, Head, Prince, Wilson, etc.) will be 27 inches. Some will be 27.5 inches, but companies usually do not deviate from these two lengths.

26 to 32 inches. Any thing shorter has been cut no matter what the gauge.
In effect an equilateral triangle is made up of two right angle triangles joined together so use Pythagoras' theorem to find the height:- 182-92 = 243 and the square root of this will be the height of the equilateral triangle which is about 15.588 cm
This hexagon is made of 6 equilateral trianges of side length 8 inches. Height of such a triangle is SQRT(8^2 - 4^2) = SQRT(48) = 6.93 inches. Area of one triangle = 4 x 6.93 = 27.71 square inches. Answer = 6 * 27.71 = 166.28 square inches
Hipparchus is considered as the father of trigonometry. he was the one who found the relation between angles of a triangle and its lengths of sides. this relation has developed into an entirely new branch in mathematics as trigonometry. so, one might as well say that he 'made' trigonometry.
Any kind of triangle can be made in a rectangle.
