The exterior angle of a triangle is always equal to the sum of the interior opposite angles. ► The medians of an equilateral triangle are equal. This is called the Pythagorean Theorem. In a right angled triangle, the three sides are called: Perpendicular, Base(Adjacent) and Hypotenuse(Opposite). A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. ► If any two angles and a non-included side of one triangle are equal to the corresponding angles and side of another triangle respectively, then the two triangles are congruent. The side opposite the right angle is called the hypotenuse (side c in the figure). The Exam will be conducted by SSC from 5th August to 24... Hello Readers, We are providing Here common geometry formulas for some basic shapes because geometry is one of the most asked ... SSC CGL Tier-I 2017 Exam Analysis Shift-2 Dear students, Today is the 5th day and second shift of SSC CGL 2017 Exam. Don't Forget to Activate the Email Subscription from your Inbox. that satisfy Pythagoras theorem are Pythagorean triplets. So, AC is the hypotenuse. SSC … ► If two sides of a triangle are unequal, the longer side has greater angle opposite to it. A) An isosceles triangle. The side that is opposite to 90 o is known as the hypotenuse. A right triangle has all the properties of a general triangle. … ► In a triangle, if the square on one side is equal to the sum of the squares on the remaining two sides, the angle opposite to the first side is a right angle. If the person purchased the land for Rs. ► If two angles of a triangle are equal, then the sides opposite to them are also equal. The sum of the other two angles of a right-angled triangle is 90 o. In the figure above, the side opposite to the right angle, BC is called the hypotenuse. ► A triangle is isosceles if and only if any two altitudes are equal. (1) Maximum area of triangle = R 2. When a triangle exactly covers other triangle i.e. The sum of the length of the two sides of a triangle is greater than the length of the third side. Two triangles are congruent if the three sides of one triangle are equal to the corresponding three sides of the other triangle. ► Two triangles are congruent if the three sides of one triangle are equal to the corresponding three sides of the other triangle. (SSS Congruence), ► Two right triangles are congruent if the hypotenuse and one side of one triangle are respectively equal to the hypotenuse and one side of the other triangle. Isosceles Triangle-In which 2 sides are equal. They all have a right angleof ninety degrees. If all the three angles of a triangle is equal to the corresponding three angles of the other triangle, then both the triangles are similar. AA-Axiom or AAA-Axiom: If two triangles have two pairs of corresponding angles equal, the triangles are similar. The following figure illustrates the basic geome… Right angle triangle: A right triangle with one side 90º. Right triangle calculator to compute side length, angle, height, area, and perimeter of a right triangle given any 2 values. The mostly occur condition for similarity is AAA similarity. For example, the sum of all interior angles of a right triangle is equal to 180°. Depending on similarities in the measurement of sides, triangles are classified as equilateral, isosceles and scalene. They are polygonsthat have three sides. Right angle : An angle of 90° is called a right angle. The exterior angles of a triangle always add up to 360 degrees. Geometry Question for SSC CGL. mirror image This property of a triangle i… These are the properties of a triangle: A triangle has three sides, three angles, and three vertices. Right angle triangle: lies on the right angle of the triangle. The relation between the sides and angles of a right triangle is the basis for trigonometry.. 5.
