Triangle a: all sides have length 12 cm. triangle b: two sides have length 10 cm, and the included angle measures 60°. triangle c: base has length 15 cm, and base angles measure 40°. triangle d: all angles measure 60°. which triangle is not a unique triangle?

Triangle C I dont want to give explanations

answer:

D. kase D pake mo ba?

Explanation:

HAHAHAHAHAHA

the answer is d. i know this is right i took the test.

All triangles are unique.

The question should read, which two of the 4 given triangles are similar.the intended answer is likely triangle D, because there are infinitely many different triangles described by D, namely all equilateral triangles.

I believe the correct answer from the choices listed above is option D. It would be triangle D where all angles measure 60 degrees that is not a unique triangle. This describes all of the equilateral triangles. Hope this answers the question. Have a nice day.

Triangle D is not a unique triangle.

Step-by-step explanation:

Triangle A: All sides have length 12 cm.

such a triangle will be a unique triangle and it will be an equilateral triangle.

Triangle B: Two sides have length 10 cm, and the included angle measures 60°.

Such a triangle will also be unique because with the help of the given angle measure and and the angles opposite to equal sides are equal we can find the measure of those two angles.

and hence we can construct a triangle with the help of these information.

Triangle C: Base has length 15 cm, and base angles measure 40°.

Such a triangle will also be unique as a unique triangle could be constructed with the help of these information.

Triangle D: All angles measure 60°.

Such a triangle will be an equilateral triangle but we can't say it will be unique as we can construct infinite number of triangles with different side lengths.

Hence such a triangle is not unique.
