Question
classify the four angles of the quadrilateral.
( angle a )
( angle b )
( angle c )
( angle d )
right
acute
obtuse
Step1: Definir los ángulos
- Ángulo recto: \(90^{\circ}\)
- Ángulo agudo: \(0^{\circ}<\theta <90^{\circ}\)
- Ángulo obtuso: \(90^{\circ}<\theta <180^{\circ}\)
Step2: Clasificar \(\angle A\)
\(\angle A = 90^{\circ}\), por lo tanto es un ángulo recto.
Step3: Clasificar \(\angle B\)
\(\angle B=60^{\circ}\), como \(0^{\circ}<60^{\circ}<90^{\circ}\), es un ángulo agudo.
Step4: Clasificar \(\angle C\)
\(\angle C = 140^{\circ}\), como \(90^{\circ}<140^{\circ}<180^{\circ}\), es un ángulo obtuso.
Step5: Clasificar \(\angle D\)
\(\angle D=70^{\circ}\), como \(0^{\circ}<70^{\circ}<90^{\circ}\), es un ángulo agudo.
