What is the formula of perimeter and area of isosceles trapezoid? In isosceles trapezoid ABCD, if ad ∥ BC, AE ⊥ BC are equal to e, and AE = ad, BC = 3aD, then ∠ B is equal to?
The circumference of isosceles trapezoid = upper base + lower base + waist + waist
Isosceles trapezoid area formula = (upper bottom + lower bottom) × height △ 2 = median line × height
45 degrees
Finding area in circumference formula of isosceles trapezoid
We know that the area is 7, the waist is 2.3, and the height is 2.5,
We know that the circumference is 7, the waist is 2, the height is 2, and the area,
Sorry, it's wrong.
Perimeter minus 2 waist length equals to the sum of the upper and lower bottom edges, and area equals to the sum of the upper and lower bottom, multiply by height and divide by two
Do you know the formula for the height of the upper and lower base and waist length of isosceles trapezoid?
If you make a bar higher, you will get a right triangle. If you solve the right triangle, you will be OK
Let the upper and lower soles be a, B and C respectively
Then one right side of a right triangle is (B-A) / 2
Pythagorean theorem: H = {(C square - [(B-A) / 2] Square)} open root sign
