Pythagorean theorem
In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle
Got it
Law of Cosines
In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles
Got it
Law of Sines
In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any shaped triangle to the sines of its angles

angle bisector theorem
In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle
perpendicular bisector theorem
In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector
Congruent Triangles
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other
hypotenuse leg
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite of the right angle
