11 Is it possible to find the angles of a triangle if I only have its sides? If so, how can I achieve this? Regarding my knowledge of triangles: Whilst I was taught trigonometry a few years ago, I …

Oct 16, 2019 · Prove that angle ABC = x. I started off by going 90 - x to find CAB. Then used co-interior angles to find AQR, and then found out BQR. I'm just curious, in this question, can I …

May 25, 2023 · 4 So SAS, SSS, ASA, AAS and RHS are reasons for congruent triangles, that means if a triangle, for example, have side lengths of 5, 6 and 8, then the triangle is unique. …

Feb 7, 2012 · What is a general procedure for "solving" a triangle—that is, for finding the unknown side lengths and angle measures given three side lengths and/or angle measures?

Apr 7, 2014 · 2 Think about similar triangles. Two similar triangles have exactly the same angles, but the sides are (generally) not the same length. That fact alone tells you that it is not …

Dec 23, 2017 · Finding an angle of a triangle with three given sides (radian) Ask Question Asked 8 years ago Modified 8 years ago

Nov 21, 2025 · Using GeoGebra, I tried to find another triangle in which these same two angles are also equal to $30^\circ$ each. So after several attempts, it appeared to me that such a …

Mar 8, 2021 · 0 good day! Excuse me, I am new to finding angles using a circle, and I don't know how to find X using trigonometric functions and everything else about triangle angles. What is …

Jan 7, 2021 · 5 At first (blue angles), notice how the $ABC$ triangle is isosceles (since $AB=BC$), and you get that the bottom angles are both $70$ (because $\frac {180-40} …

Oct 22, 2020 · I remember there's an identity which says that the sum of the exterior angles of a triangle add up to $360^ {\circ}$. In this case it would mean that: $3\alpha+120+180 …
