Quadrilateral as it is a four-sided ploygon, having 4 edges and corners
Answer: It should equal this ,-2+49÷(-7)=-9 !
Step-by-step explanation:
Answer:
x=117
Step-by-step explanation:
since there is 2 angles that they already give you the measurements with. you try to solve the 101 angle and subtract 180-101= 79. this is the angle beside 101. since a triangle is equal to 180 degrees; you add the 38 and 79 which equals 117. you subtract 180-117=63. That is the other angle on the inside of the triangle.
Step-by-step explanation:
Let ABC be an isosceles triangle with sides AC and BC of equal length.
We need to prove that the medians AD and BE are of equal length.
Consider the triangles ADC and BEC.
They have two congruent sides that include congruent angles.
Indeed, AC = BC by the condition, because the triangle ABC is isosceles.
Since the lateral sides AC and BC are of equal length, their halves EC
and DC are of equal length too: EC = DC.
Finally, the angle ECD is the common angle.
Thus, the triangles ADC and BEC are congruent, in accordance to the
postulate P1 (SAS) (see the lesson Congruence tests for triangles of the
topic Triangles in the section Geometry in this site).
Hence, the medians AD and BE are of equal length as the corresponding sides
of these triangles.
The proof is completed.
