15' 25"
If myunderstanding is correct, then the one dash (') refers to minutes and two dashes (") refer to seconds. There are 60 seconds in a minute and 60 minutes in a degree so that 1" is 1/3600 of a degree.
That they are both identical in size and angles
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
an isosceles triangle is a triangle that means two of the triangles sides have the same length and two angles are the same
I'm not sure what you mean but the angle sum (what all the interior angles add up to) is 180 degrees.
CPCTC is an acronym for the phrase 'corresponding parts of congruent triangles are congruent' It means that once we know that two triangles are congruent, we know that all corresponding sides and angles are congruent.
Having two dashes on a triangle is common notation in arithmetic, specifically geometry. Two dashes mean that there is one dash each on two different lines of the triangle, and this indicates that the two lines are of equal length. This also means that the triangle is an isosceles triangle.
That they are both identical in size and angles
If you mean trigonometry then it is the working properties of triangles.
Type your answer here... what does dashes mean
Trigonometry is the study involving the measurements of the lengths of sides and the angles of triangles (or trigons)..
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
It refers to Pythagoras. More often than not, it refers to statements about the measures of the sides of right angles triangles.

All equiangular triangles are similar, but not congruent. They all have three 60 degree angles. This does not mean that they all have the same side lengths though. Therefore, they are only similar, not congruent.
