Example 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°.Web

Using trapeze instead of trapezium, or vice versa, can lead to confusion and inaccuracies in mathematical calculations. For instance, if someone were to incorrectly refer to a trapezium as a trapeze while solving a geometry problem, it could result in an incorrect answer due to the fundamental differences between these two shapes. Precision and ...Web

The lead–zinc ore is a typical low-grade complex polymetallic sulphide ore.
