Are all equiangular triangles similar? justify your answer

Answer from: melmar76

one can get similar triangles by AA, namely Angle Angle, two angles are the same on both triangles.

now if two triangles are equal in both triangles, the last remaining triangle by definition must equal the other remaining on the other triangle, so we really have AAA.

Equiangular triangles, have AAA and therefore also AA, thus similar.

Answer from: sugandiwoodbine

Yes, all equiangular triangles are similar.

Step-by-step explanation:

We have been given an statement. We are asked to determine whether our given statement is true or not.

Statement: All equi-angular triangles similar.

We know an equiangular triangle has all three interior angles of equal measure, that is, each angle measures 60 degrees.

All equiangular triangles will have each interior angle of 60 degrees. By Angle-Angle-Angle similarity all equiangular triangle are similar, therefore, our given statement is true.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
Ineed as soon as possible ! what is the approximate length of the minor arc de
