Question 1

What is a 45 degree angle?

Accepted Answer

A 45-degree angle has several key properties:It's an acute angle:  Acute angles measure less than 90 degrees.It's half a right angle: A right angle measures 90 degrees, so a 45-degree angle is exactly half of that.In an isosceles right triangle:  A 45-degree angle is always found in an isosceles right triangle.  This is a right triangle (containing one 90-degree angle) where the two legs (the sides that form the right angle) are of equal length. The other two angles in this triangle are both 45 degrees.Trigonometric ratios:  For a 45-degree angle (often denoted as π/4 radians):sin(45°) = cos(45°) = √2 / 2  ≈ 0.707tan(45°) = 1Geometric constructions: A 45-degree angle is easily constructed using a compass and straightedge by bisecting a right angle.Applications:  45-degree angles appear frequently in architecture, engineering, and design, often for symmetry and structural reasons.  They're also common in many geometric problems and calculations.
