    what section is this meant to cover? are you doing trig? law of sines or cosines?

    that is, what are they expecting as answer, a numeric value? an expression?

    i think a value. in degrees or something. The "ABC" has that little angle sign in front of it

    nope. its called Sides and Angles of Congruent Triangles

    ok... have you covered SOH CAH TOA yet? that is \(sin(\theta)=\cfrac{opposite}{hypotenuse} \qquad \qquad % cosine cos(\theta)=\cfrac{adjacent}{hypotenuse} \\ \quad \\ % tangent tan(\theta)=\cfrac{opposite}{adjacent}\)

    because... congruence is not going to get you far on this one, nor similarility

    You're in the geometry course right? Or? If so, I believe SOH CAH TOA is supposed to be covered towards the end of algebra 1.

    After you get the answer to your initial question I can explain SOH CAH TOA. Because if u answer using that when it has not been taught or covered so far, that will be suspicious or something.

    so.. I'd think this exercise may not apply to you then since you have not covered that, and I don't see how congruence will help on this triangle

    yes... is on a grid, I can see that much so each vertex, A, B and C, have some coordinate to get their segment length, you'd need the distance formula that's simple enough but once you get the segment's length, you'd need to apply ..... hmm I'd use the law of cosines, to get any of the angles and you haven't covered any of that, thus, it may not apply to you

    may well be, but you haven't covered the subject yet so... not much you could do there, without covering the subject the teacher hasn't done it is not very helpful if one is covering say... chapter 3 and dispenses exercises for students for chapter 6 if you're in say chapter 3, then that's what needs to be assigned

    one of the criteria is this though : Measure the angles of ABC and its images.

    @Setsuna-Yuregeshi click on [Draw] then click on [copy previous drawing] scroll up, pick it by clicking, then draw on it or delete from it by using the [selection] tool and pressing delete key

    In the beginning you said you needed to measure ABC and ACB, look at @jdoe0001's drawings. He tells you which drawings are for which angles...

    either line if you put on one, it'll give the same angle as if you were to put it on the other same angle
