Answer:
In rhombus abcd, measure ∠b = 110°, ∠c = 70° and ∠d = 110°.
Explanation:
What is a rhombus?
A quadrilateral having all sides equal is known as a rhombus. It is also known as equilateral quadrilateral.
According to the property of rhombus:
The opposite angles of a rhombus are congruent.Hence ∠a ≅ ∠c∴m ∠c = 70°
According to the property of rhombus:
The adjacent angles of a rhombus are supplementary.
∠a+∠b=180°70°+∠b=180°
∴m ∠b=110°
As opposite angles of a rhombus are congruent,
∠b≅∠d
∴m ∠d=110°
