Given:
Different types of congruence postulates.
To find:
Which cannot be used to prove that two triangles are congruent?
Solution:
According to AAS congruence postulate, if two angles and a non including sides of two triangles are congruent, then triangles are congruent.
According to SAS congruence postulate, if two sides and an including angle of two triangles are congruent, then triangles are congruent.
According to SSS congruence postulate, if all three sides of two triangles are congruent, then triangles are congruent.
AAA states that all three angles of two triangles are equal and no information about sides.
So, it is a similarity postulate not congruent postulate. According to AAA two triangles are similar not congruent.
Therefore, the correct option is D.
One hundred and thirty five million, 7 hundred and ninety one thousand and three hundred and fifty seven point nine one
5 is the GCF. 5 is the only number that, when multiplied by another number, goes evenly into both 35 and 45.
35 = 5*7
45 = 5*9
The area of the entire sector is
The area of the triangle OAB is .
So, the area of the segment is
