Angle from Any Two Sides We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall?
<p>To solve the problem, we will use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two
1 In a right-angled triangle ABC, ∠ABC = 90°, D is a point on AB, E F is the perpendicular bisector of AD, intersecting AC at E with F being the foot of the Aperpendicular, and the extension of E D intersects the extension of CB at point G.F EProve: EG = EC.D G B...
