WebFeb 24, 2024 · 1. rectangle ABCD, BD & AC are the diagonals. ∠ABD =36 degrees 2. ∠ABD= ∠BDC = 36 - alternate interior angles 3. ∠DBC = 90 - 36 = 54. ∠DBC =∠ADB = ∠BCA = 54 4. Now we know that the triangle formed between the two diagonals is a isosceles triangle because of base angle theorem. 5. 180 - 54*2 = 72 degrees I hope this helps! Advertisement A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.
