explaining on Instagram: "This diagram beautifully explains why the sum of all angles in a triangle is always 180° 📐✨ Each corner of the triangle is shown with different colors — green, blue, and red. When these three angles are placed together along a straight line (as shown at the top), they form a straight angle, which equals 180°. Geometrically, if you extend one side of the triangle and draw a line parallel to the opposite side, using the rules of alternate interior and corresponding angle

mathswithmuza on Instagram: "Trigonometric functions describe the relationships between the angles and sides of a triangle, particularly a right-angled triangle. The six main trigonometric functions are sine, cosine, tangent, cosecant, secant, and cotangent. Each of these functions relates an angle to specific ratios of the triangle’s sides—for example, the sine of an angle is the ratio of the opposite side to the hypotenuse, while the cosine is the ratio of the adjacent side to the hypotenuse.
