A trapezoid. 8D
A pyramid has 4 straIGHT SIDES
4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.
diagonal can only be found if two sides are known, imagine if you only have one known side ,the other side could be of any length and therefore the diagonal could be any length. if two sides are known then use pythagoras, as the two sides make up the 'adjacent' and 'opposite' side of a right angled triangle e.g. side a=2, side b=4 side c is square root of 2x2 plus 4x4 i.e root of 4+ 16=20 which is approx 4.47
If its sides are 3 by 4 then using Pythagoras its diagonal is 5 feet
The two states have only four straight sides are Wyoming and Colorado.
A trapezoid. 8D
There are 4
A heptagon has 4 diagonal lines and 7 sides and it has 2 congruent diagonal lines and 2 congruent triangles
A pyramid has 4 straIGHT SIDES
4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.
it has 4 sides
By the Pythagorean Theorem, the diagonal is the hypotenuse of the right triangle formed by the diagonal and the two included sides. c2 = a2 + b2 so the diagonal is the square root of the sum of the squares of the rectangle's length and width. Example : for a rectangle 4 x 3, the diagonal is sqrt(32 + 42) = sqrt (25) = 5
diagonal can only be found if two sides are known, imagine if you only have one known side ,the other side could be of any length and therefore the diagonal could be any length. if two sides are known then use pythagoras, as the two sides make up the 'adjacent' and 'opposite' side of a right angled triangle e.g. side a=2, side b=4 side c is square root of 2x2 plus 4x4 i.e root of 4+ 16=20 which is approx 4.47
You need to know the lengths of the sides and at least one angle or the length of a diagonal.
According to the "3-4-5" law of right triangles, if the two sides of the triangle are 3 units and 4 units, the hypotenuse must be 5 units. So a diagonal must be 15 inches. The sides are 3 * 3 and 3 * 4, so the diagonal is 3 * 5.
If its sides are 3 by 4 then using Pythagoras its diagonal is 5 feet
