Plz mark me brainliest

Step-by-step explanation:

Answer 2

Answer:

6) 90 degree

7)Properties of Exterior Angle

8) Statement of pythogra's theoram

9)Congruence of Triangles

10) congruent trangles

Step-by-step explanation:

6) When an angle is its own supplement, that means that the angle, plus itself, will equal 180 degrees.

so , let the angles be x

= x + x = 180

= 2x = 180

= x = 180/2

= x = 90

7)

The properties of the exterior angle is given as follows:

The properties of the exterior angle is given as follows:The exterior angle of a given triangle equals the sum of the opposite interior angles of that triangle.

The properties of the exterior angle is given as follows:The exterior angle of a given triangle equals the sum of the opposite interior angles of that triangle.If an equivalent angle is taken at each vertex of the triangle, the exterior angles add to 360° in all the cases. In fact, this statement is true for any given convex polygon and not just triangles.

8) Pythagoras Theorem states that the in a right angled triangle Square of the length of the hypotenuse of the right angled triangle is equal to the sum of the squares of the lengths of other two sides of the right angled triangle. ... This satisfies the condition for Pythagorean triplets a2=b2+c2.

9)Congruence of Triangles Criterion

Congruence of Triangles CriterionSSS Congruence Rule (Side – Side – Side)

Congruence of Triangles CriterionSSS Congruence Rule (Side – Side – Side)Two triangles are said to be congruent if all the sides of a triangle are equal to all the corresponding sides of another triangle.

SAS Congruence Rule (Side – Angle – Side)

SAS Congruence Rule (Side – Angle – Side)Two triangles are said to be congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle.

ASA Congruence Rule ( Angle – Side – Angle )

ASA Congruence Rule ( Angle – Side – Angle )Two triangles are said to be congruent if two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

10)

congruent triangles are a pair of triangles in which all three sides are corresponding. In congruent triangles, the angles should also be equal or congruent. In congruent triangles, all the corresponding parts are equal.

question 1 to 6 are in another answer !!

Keep questioning !!
