![]() ![]() The triangle below is named ABC.Ī triangle has three angles. To name a triangle we often use its vertices (the name of the endpoints). The line segments intersect in their endpoints. The area of an isosceles triangle is the space occupied by the boundary of the isosceles triangle.A triangle is composed of three line segments. What is the Area of the Isosceles Triangle? If the isosceles triangle has equal side a and unequal side b then,ģ. The perimeter of an isosceles triangle is equal to the sum of its three side lengths. What is the Perimeter of an Isosceles Triangle? What is Isosceles Triangle?Īn isosceles triangle is a triangle with at least two sides equal and the corresponding angles opposite to them are also equal. Q5: Find the area of an isosceles triangle whose base is 12 cm and equal sides are 13 cm. Q4: If the perimeter of an isosceles triangle is 25 cm and the unequal side is 5 cm. Also state what type of the triangle is this based on the value of all the three angles. Q3: If the equal angles of an isosceles triangle measures 60°, find the third angle. Q2: If the height of a isoceles triangle is 4 cm and base is 6 cm find the length of equal sides. Q1: What is the perimeter of a field whose shape is in form of a triangle having two equal sides of 10m and third side being 5m. Hence, the area of the given isosceles triangle is 168 sq. The height, perimeter, and area are the three basic formulas of an isosceles triangle, which are discussed below. If we have an Isosceles triangle ABC then,ĪB = AC ⟺ ∠ABC = ∠ADC Isosceles Triangles Formulas “If two angles in any isosceles triangle are equal then the side opposite to them are also equal.” The converse of this theorem is also true which states that “If two sides in any isosceles triangle are equal then the angle opposite to them are also equal.” The Isosceles Triangle Theorem states that, The perpendicular drawn from the apex angle is also known as the line of symmetry as it divides the isosceles triangle into two congruent triangles.The perpendicular drawn from the apex angle bisects the base of the isosceles triangle and the apex angle.The angle between the legs of an isosceles triangle is called the apex angle or vertex angle.In an isosceles triangle, the two sides of equal length are called the legs, and the third side of the triangle is called the base. ![]() An isosceles triangle will always have at least two equal sides and two equal angles.The following are some important characteristics of an isosceles triangle: Triangle with angles 35°, 35° and 110°, etc.Some examples of isosceles obtuse triangles are, Examples of isosceles right triangles are,Īn isosceles triangle in which any one angle is obtuse angles and the other two are acute angles is called an Isosceles Acute triangle. Triangle with angles 65°, 65° and 50°, etc.Īn isosceles triangle that has a right angle is called an Isosceles Right triangle.Software Engineering Interview Questions.Top 10 System Design Interview Questions and Answers.Top 20 Puzzles Commonly Asked During SDE Interviews.Commonly Asked Data Structure Interview Questions.Top 10 algorithms in Interview Questions.Top 20 Dynamic Programming Interview Questions.Top 20 Hashing Technique based Interview Questions.Top 50 Dynamic Programming (DP) Problems.Top 20 Greedy Algorithms Interview Questions.Top 100 DSA Interview Questions Topic-wise.
