In right angled triangle, the base angle is 45°, whereas the base length is 3 dm, the length of perpendicular is?
Answer: 3 dm
Explanation
Given a right-angled triangle with a base angle of 45°, it's an isosceles right triangle, meaning the base and perpendicular are equal.
Base length = 3 dm
Perpendicular length = 3 dm
