No, it means they have either 2 sides and 1 angle congruent, 2 angles congruent, 2 angles and a side congruent, or 3 sides congruent.
This traingle is an equilateral traingle: which consists of all the three sides and angles to be congruent. The angles inside the triangle, just like any normal traingle, add up to be 180 degrees. The opposite of this traingle is the Scalene triangle which has all the three sides to be Uncongruent and has different angles. All the angles of ALL traingles still add up to 180 Degrees. The Isoceles triangle consists of two equal sides and one extravagantly large one side. Therefore, because of the previous properties, an isosceles traingle has two congruent angles and usually one obtuse or acute angle. The last triangle, the right triangle, has one right angle. It is the only triangle that is capable with triginomical ratios and the Pythagorean Theorem.
How about an isosceles triangle of which 2 of its 3 sides are congruent and 2 of its 3 angles are congruent
