The diagonal of a rectangle makes an angle of 70 degrees from one of its sides Find the angle between the diagonals of this rectangle
To solve this problem, remember that the diagonals are halved by the intersection point. When the diagonals intersect, we get an isosceles triangle. An isosceles triangle has equal angles at the base. Since one angle is 70 degrees, the second is 70 degrees. Let’s calculate the third angle in this triangle, the angle between the diagonals. In a triangle, the sum of the lengths of all sides is 180 degrees.
180- (70 + 70) = 180-140 = 40 degrees.
Answer: 40 degrees.
