Pythagoras was a person, pythagorean refers to his mathematical theories - principally his theorems about the measures of the sides of a right angled triangle.
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..
A right angle triangle has an hypotenuse which is its longest side, an adjacent side and an opposite side.
It depends on what else you know about the triangle.
The two triangle congruence theorems are the AAS(Angle-Angle-Side) and HL(Hypotenuse-Leg) congruence theorems. The AAS congruence theorem states that if two angles and a nonincluded side in one triangle are congruent to two angles and a nonincluded side in another triangle, the two triangles are congruent. In the HL congruence theorem, if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, the two triangles are congruent.
HA, LA, HL, LL [APEX]
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
LL , La , HL and Ha
If the hypotenuse and a leg of two right triangles are the same measure, the triangles are congruent
There is nothing specific folloing right triangle congruence theorem. It depends on the order in whih the syllabus is taught.
there are 4 types of congruence theorem-: ASA,SSS,RHS,SAS
They are theorems that specify the conditions that must be met for two triangles to be congruent.
the congruence theorems or postulates are: SAS AAS SSS ASA
right triangle
LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
HA Congruence Theorem says: If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two right triangles are congruent.
