Answer:

Step-by-step explanation:

● first one:

The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.

STP is one of them so this statement is true.

● second one:

If ST and PT were equal this would be a square not a rhombus.

● third one:

If SPQ was a right angle, this woukd be a square.

● fourth one:

Again if the diagonals SQ and PR were equal, this would be a square.

If = 80°, and m∠BED = 25°, what is ? 55° 30° 65° 20°

Tomtit [17]

The complete question in the attached figure

we know that
The measure of the external angle is the semidifference of the arcs that it covers.
so
m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2m∠BED
mBD=80-2*25--------> mBD=30°

the answer is
mBD=30°
