Question
Prove that ∠ ABC ≅ ∠ ADC
Hint:
Find the congruence rule used and then find the equal angles.
The correct answer is: ∠ ABC ≅ ∠ CDA (corresponding parts of congruent triangles)
Complete step by step solution:
From the figure,
In △ABC and △CDA, we have
AB = CD (given)
AD = CB (given)
AC = AC (common side)
Hence △ABC⩭ △CDA by SSS congruence rule.
⇒ ∠ ABC ≅ ∠ CDA (corresponding parts of congruent triangles)

The x + 2 = 6 x+2=6x, plus, 2, equals 6 contains a variable. We call this type of equation with a variable an algebraic equation. Finding the variable value that will result in a true equation is typically our aim when solving an algebraic equation.
¶Variables or constants are the two types of measurable quantities. A variable is a quantity with a varying value, and the constant value is nothing but a constant.
¶Steps to writing Variable Equation
1) Identify the variables that represent the unknowns.
2) Convert the issue into variable expressions in algebra.
3) Determine the variables' values to solve the equations for their true values.
