We need a few pieces of the puzzle before we can find the measure of x. They ultimately want to find the measure of that exterior angle. There’s actually at least three different ways that you can answer this problem. Find a piece at a time and put them together until you reach your answer! You have to look at these problems as “puzzles” because sometimes you need to find a part that they are not asking for in order to find the final result. Let’s see if we can put these properties to work and answer a few questions. So, in EVERY equilateral triangle, the angles are always 60°.

This is because all angles in a triangle always add up to 180°and if you divide this amongst three angles, they have to each equal 60°. The angles, however, HAVE to all equal 60°. The sides can measure anything as long as they are all the same. When all angles are congruent, it is called equiangular. In an equilateral triangle, all sides are congruent AND all angles are congruent. Here are some diagrams that usually help with understanding.

Since two sides are congruent, it also means that the two angles opposite those sides are congruent. Well, some of these types of triangles have special properties!Īn isosceles triangle has two sides that are congruent.

Write a C program to find maximum between three numbers.Write a C program to find maximum between two numbers.Required knowledgeīasic C programming, Relational operators, Logical operators List of if.else programming exercises In this exercise we will focus to control program flow using if.else statements.Īlways feel free to drop your queries and suggestions below in the comments section. Relational and logical operators supports this comparison.Ĭ language supports three variants of if statement.Īs a programmer you must have a good control on program execution flow. It is used to compare things and take some action based on the comparison. If statement works like “If condition is met, then execute the task”. For example – if user inputs valid account number and pin, then allow money withdrawal. It is used to take an action based on some condition.
