Question

3. ABCD is a rectangle AC is diagonal. find the nature of triangle ACD.give reasons​

Answer 1

Answer:a right angle triangle

Step-by-step explanation:

Given that it is a rectangle

All angles of a rectangle are 90°

Digonal bisects it into 2 congurent triangles

1 angle is 90° hence it is a right angle triangle

Answer 2

Answer:

right angled triangle

Step-by-step explanation:

in quadrilateral ABCD,

quadrilateral ABCD is a rectangle

according to the property of rectangle:-

[all angles of a rectangle are supplementary.]

we can conclude that,

if a diagonal is passed from two points (AD)

"ΔABC will formed of 90° will form.

now,

we know that all angles of rectangle are supplementary then,

angle "C" is of 90°

hence,

ΔACD is a right angled triangle.

if that answer is helful to you please mark me as brainliest
